It also counts + as the successor of the GNU Library Public License, version 2, hence + the version number 2.1.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the +Free Software Foundation and other authors who decide to use it. You +can use it too, but we suggest you first think carefully about whether +this license or the ordinary General Public License is the better +strategy to use in any particular case, based on the explanations below. + + When we speak of free software, we are referring to freedom of use, +not price. Our General Public Licenses are designed to make sure that +you have the freedom to distribute copies of free software (and charge +for this service if you wish); that you receive source code or can get +it if you want it; that you can change the software and use pieces of +it in new free programs; and that you are informed that you can do +these things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know +that what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and +is quite different from the ordinary General Public License. We use +this license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the "Lesser" General Public License because it +does Less to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it becomes +a de-facto standard. To achieve this, non-free programs must be +allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of +free software. For example, permission to use the GNU C Library in +non-free programs enables many more people to use the whole GNU +operating system, as well as its variant, the GNU/Linux operating +system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run +that program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + + GNU LESSER GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library or other +program which contains a notice placed by the copyright holder or +other authorized party saying it may be distributed under the terms of +this Lesser General Public License (also called "this License"). +Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also combine or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer system, + rather than copying library functions into the executable, and (2) + will operate properly with a modified version of the library, if + the user installs one, as long as the modified version is + interface-compatible with the version that the work was made with. + + c) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + d) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the materials to be distributed need not include anything that is +normally distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties with +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Lesser General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN +WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY +AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU +FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR +CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE +LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING +RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A +FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF +SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH +DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Libraries + + If you develop a new library, and you want it to be of the greatest +possible use to the public, we recommend making it free software that +everyone can redistribute and change. You can do so by permitting +redistribution under these terms (or, alternatively, under the terms of the +ordinary General Public License). + + To apply these terms, attach the following notices to the library. It is +safest to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least the +"copyright" line and a pointer to where the full notice is found. + + <one line to give the library's name and a brief idea of what it does.> + Copyright (C) <year> <name of author> + + This library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + This library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Thank you. + +ADDING A NEW FILE +================= + +There are two sets of files: Those that are "required" will be +included in the library for all configurations, while those +that are "optional" will be included in the library only if "needed." + +To add a new required file, edit Makefile.in to add the source file +name to CFILES and the object file to REQUIRED_OFILES. + +To add a new optional file, it must provide a single function, and the +name of the function must be the same as the name of the file. + + * Add the source file name to CFILES in Makefile.in and the object + file to CONFIGURED_OFILES. + + * Add the function to name to the funcs shell variable in + configure.ac. + + * Add the function to the AC_CHECK_FUNCS lists just after the + setting of the funcs shell variable. These AC_CHECK_FUNCS calls + are never executed; they are there to make autoheader work + better. + + * Consider the special cases of building libiberty; as of this + writing, the special cases are newlib and VxWorks. If a + particular special case provides the function, you do not need + to do anything. If it does not provide the function, add the + object file to LIBOBJS, and add the function name to the case + controlling whether to define HAVE_func. + +Finally, in the build directory of libiberty, configure with +"--enable-maintainer-mode", run "make maint-deps" to update +Makefile.in, and run 'make stamp-functions' to regenerate +functions.texi. + +The optional file you've added (e.g. getcwd.c) should compile and work +on all hosts where it is needed. It does not have to work or even +compile on hosts where it is not needed. + +ADDING A NEW CONFIGURATION +========================== + +On most hosts you should be able to use the scheme for automatically +figuring out which files are needed. In that case, you probably +don't need a special Makefile stub for that configuration. + +If the fully automatic scheme doesn't work, you may be able to get +by with defining EXTRA_OFILES in your Makefile stub. This is +a list of object file names that should be treated as required +for this configuration - they will be included in libiberty.a, +regardless of whatever might be in the C library. diff --git a/libiberty/_doprnt.c b/libiberty/_doprnt.c new file mode 100644 index 000000000..ca97bc8c5 --- /dev/null +++ b/libiberty/_doprnt.c @@ -0,0 +1,296 @@ +/* Provide a version of _doprnt in terms of fprintf. + Copyright (C) 1998, 1999, 2000, 2001, 2002 Free Software Foundation, Inc. + Contributed by Kaveh Ghazi (ghazi@caip.rutgers.edu) 3/29/98 + +This program is free software; you can redistribute it and/or modify it +under the terms of the GNU General Public License as published by the +Free Software Foundation; either version 2, or (at your option) any +later version. + +This program is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

It also counts +as the successor of the GNU Library Public License, version 2, hence the +version number 2.1.] +@end display + +@appendixsubsec Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software---to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software---typically libraries---of the Free +Software Foundation and other authors who decide to use it. You can use +it too, but we suggest you first think carefully about whether this +license or the ordinary General Public License is the better strategy to +use in any particular case, based on the explanations below. + + When we speak of free software, we are referring to freedom of use, +not price. Our General Public Licenses are designed to make sure that +you have the freedom to distribute copies of free software (and charge +for this service if you wish); that you receive source code or can get +it if you want it; that you can change the software and use pieces of it +in new free programs; and that you are informed that you can do these +things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know +that what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and +is quite different from the ordinary General Public License. We use +this license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the @dfn{Lesser} General Public License because it +does @emph{Less} to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it becomes +a de-facto standard. To achieve this, non-free programs must be +allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of +free software. For example, permission to use the GNU C Library in +non-free programs enables many more people to use the whole GNU +operating system, as well as its variant, the GNU/Linux operating +system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run +that program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +``work based on the library'' and a ``work that uses the library''. The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + +@iftex +@appendixsubsec TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION +@end iftex +@ifinfo +@center GNU LESSER GENERAL PUBLIC LICENSE +@center TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION +@end ifinfo + +@enumerate 0 +@item +This License Agreement applies to any software library or other program +which contains a notice placed by the copyright holder or other +authorized party saying it may be distributed under the terms of this +Lesser General Public License (also called ``this License''). Each +licensee is addressed as ``you''. + + A ``library'' means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The ``Library'', below, refers to any such software library or work +which has been distributed under these terms. A ``work based on the +Library'' means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term ``modification''.) + + ``Source code'' for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + +@item +You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + +@item +You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + +@enumerate a +@item +The modified work must itself be a software library. + +@item +You must cause the files modified to carry prominent notices +stating that you changed the files and the date of any change. + +@item +You must cause the whole of the work to be licensed at no +charge to all third parties under the terms of this License. + +@item +If a facility in the modified Library refers to a function or a +table of data to be supplied by an application program that uses +the facility, other than as an argument passed when the facility +is invoked, then you must make a good faith effort to ensure that, +in the event an application does not supply such function or +table, the facility still operates, and performs whatever part of +its purpose remains meaningful. + +(For example, a function in a library to compute square roots has +a purpose that is entirely well-defined independent of the +application. Therefore, Subsection 2d requires that any +application-supplied function or table used by this function must +be optional: if the application does not supply it, the square +root function must still compute square roots.) +@end enumerate + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + +@item +You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + +@item +You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + +@item +A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a ``work that uses the Library''. Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a ``work that uses the Library'' with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a ``work that uses the +library''. The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a ``work that uses the Library'' uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + +@item +As an exception to the Sections above, you may also combine or +link a ``work that uses the Library'' with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + +@enumerate a +@item +Accompany the work with the complete corresponding +machine-readable source code for the Library including whatever +changes were used in the work (which must be distributed under +Sections 1 and 2 above); and, if the work is an executable linked +with the Library, with the complete machine-readable ``work that +uses the Library'', as object code and/or source code, so that the +user can modify the Library and then relink to produce a modified +executable containing the modified Library. (It is understood +that the user who changes the contents of definitions files in the +Library will not necessarily be able to recompile the application +to use the modified definitions.) + +@item +Use a suitable shared library mechanism for linking with the Library. A +suitable mechanism is one that (1) uses at run time a copy of the +library already present on the user's computer system, rather than +copying library functions into the executable, and (2) will operate +properly with a modified version of the library, if the user installs +one, as long as the modified version is interface-compatible with the +version that the work was made with. + +@item +Accompany the work with a written offer, valid for at +least three years, to give the same user the materials +specified in Subsection 6a, above, for a charge no more +than the cost of performing this distribution. + +@item +If distribution of the work is made by offering access to copy +from a designated place, offer equivalent access to copy the above +specified materials from the same place. + +@item +Verify that the user has already received a copy of these +materials or that you have already sent this user a copy. +@end enumerate + + For an executable, the required form of the ``work that uses the +Library'' must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the materials to be distributed need not include anything that is +normally distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies the +executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + +@item +You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + +@enumerate a +@item +Accompany the combined library with a copy of the same work +based on the Library, uncombined with any other library +facilities. This must be distributed under the terms of the +Sections above. + +@item +Give prominent notice with the combined library of the fact +that part of it is a work based on the Library, and explaining +where to find the accompanying uncombined form of the same work. +@end enumerate + +@item +You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + +@item +You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + +@item +Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties with +this License. + +@item +If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + +@item +If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + +@item +The Free Software Foundation may publish revised and/or new +versions of the Lesser General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +``any later version'', you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + +@item +If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + +@iftex +@heading NO WARRANTY +@end iftex +@ifinfo +@center NO WARRANTY +@end ifinfo + +@item +BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY ``AS IS'' WITHOUT WARRANTY OF ANY +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE.

It has evolved +over years but does not have its own version number nor release schedule. + +Possibly the easiest way to use @libib{} in your projects is to drop the +@libib{} code into your project's sources, and to build the library along +with your own sources; the library would then be linked in at the end. This +prevents any possible version mismatches with other copies of libiberty +elsewhere on the system. + +Passing @option{--enable-install-libiberty} to the @command{configure} +script when building @libib{} causes the header files and archive library +to be installed when @kbd{make install} is run. This option also takes +an (optional) argument to specify the installation location, in the same +manner as @option{--prefix}. + +For your own projects, an approach which offers stability and flexibility +is to include @libib{} with your code, but allow the end user to optionally +choose to use a previously-installed version instead. In this way the +user may choose (for example) to install @libib{} as part of GCC, and use +that version for all software built with that compiler. (This approach +has proven useful with software using the GNU @code{readline} library.) + +Making use of @libib{} code usually requires that you include one or more +header files from the @libib{} distribution. (They will be named as +necessary in the function descriptions.) At link time, you will need to +add @option{-liberty} to your link command invocation. + + +@node Overview +@chapter Overview + +Functions contained in @libib{} can be divided into three general categories. + + +@menu +* Supplemental Functions:: Providing functions which don't exist + on older operating systems. + +* Replacement Functions:: These functions are sometimes buggy or + unpredictable on some operating systems. + +* Extensions:: Functions which provide useful extensions + or safety wrappers around existing code. +@end menu + +@node Supplemental Functions +@section Supplemental Functions +@cindex supplemental functions +@cindex functions, supplemental +@cindex functions, missing + +Certain operating systems do not provide functions which have since +become standardized, or at least common. For example, the Single +Unix Specification Version 2 requires that the @code{basename} +function be provided, but an OS which predates that specification +might not have this function. This should not prevent well-written +code from running on such a system. + +Similarly, some functions exist only among a particular ``flavor'' +or ``family'' of operating systems. As an example, the @code{bzero} +function is often not present on systems outside the BSD-derived +family of systems. + +Many such functions are provided in @libib{}. They are quickly +listed here with little description, as systems which lack them +become less and less common. Each function @var{foo} is implemented +in @file{@var{foo}.c} but not declared in any @libib{} header file; more +comments and caveats for each function's implementation are often +available in the source file. Generally, the function can simply +be declared as @code{extern}. + + + +@node Replacement Functions +@section Replacement Functions +@cindex replacement functions +@cindex functions, replacement + +Some functions have extremely limited implementations on different +platforms. Other functions are tedious to use correctly; for example, +proper use of @code{malloc} calls for the return value to be checked and +appropriate action taken if memory has been exhausted. A group of +``replacement functions'' is available in @libib{} to address these issues +for some of the most commonly used subroutines. + +All of these functions are declared in the @file{libiberty.h} header +file. Many of the implementations will use preprocessor macros set by +GNU Autoconf, if you decide to make use of that program. Some of these +functions may call one another. + + +@menu +* Memory Allocation:: Testing and handling failed memory + requests automatically. +* Exit Handlers:: Calling routines on program exit. +* Error Reporting:: Mapping errno and signal numbers to + more useful string formats. +@end menu + +@node Memory Allocation +@subsection Memory Allocation +@cindex memory allocation + +The functions beginning with the letter @samp{x} are wrappers around +standard functions; the functions provided by the system environment +are called and their results checked before the results are passed back +to client code.

This structure has a small fixed size; it records the status +of the obstack and how to find the space in which objects are allocated. +It does not contain any of the objects themselves. You should not try +to access the contents of the structure directly; use only the functions +described in this chapter. +@end deftp + +You can declare variables of type @code{struct obstack} and use them as +obstacks, or you can allocate obstacks dynamically like any other kind +of object. Dynamic allocation of obstacks allows your program to have a +variable number of different stacks. (You can even allocate an +obstack structure in another obstack, but this is rarely useful.) + +All the functions that work with obstacks require you to specify which +obstack to use. You do this with a pointer of type @code{struct obstack +*}. In the following, we often say ``an obstack'' when strictly +speaking the object at hand is such a pointer. + +The objects in the obstack are packed into large blocks called +@dfn{chunks}. The @code{struct obstack} structure points to a chain of +the chunks currently in use. + +The obstack library obtains a new chunk whenever you allocate an object +that won't fit in the previous chunk. Since the obstack library manages +chunks automatically, you don't need to pay much attention to them, but +you do need to supply a function which the obstack library should use to +get a chunk. Usually you supply a function which uses @code{malloc} +directly or indirectly. You must also supply a function to free a chunk. +These matters are described in the following section. + +@node Preparing for Obstacks +@section Preparing for Using Obstacks + +Each source file in which you plan to use the obstack functions +must include the header file @file{obstack.h}, like this: + +@smallexample +#include <obstack.h> +@end smallexample + +@findex obstack_chunk_alloc +@findex obstack_chunk_free +Also, if the source file uses the macro @code{obstack_init}, it must +declare or define two functions or macros that will be called by the +obstack library. One, @code{obstack_chunk_alloc}, is used to allocate +the chunks of memory into which objects are packed. The other, +@code{obstack_chunk_free}, is used to return chunks when the objects in +them are freed. These macros should appear before any use of obstacks +in the source file. + +Usually these are defined to use @code{malloc} via the intermediary +@code{xmalloc} (@pxref{Unconstrained Allocation, , , libc, The GNU C Library Reference Manual}). This is done with +the following pair of macro definitions: + +@smallexample +#define obstack_chunk_alloc xmalloc +#define obstack_chunk_free free +@end smallexample + +@noindent +Though the memory you get using obstacks really comes from @code{malloc}, +using obstacks is faster because @code{malloc} is called less often, for +larger blocks of memory. @xref{Obstack Chunks}, for full details. + +At run time, before the program can use a @code{struct obstack} object +as an obstack, it must initialize the obstack by calling +@code{obstack_init}. + +@comment obstack.h +@comment GNU +@deftypefun int obstack_init (struct obstack *@var{obstack-ptr}) +Initialize obstack @var{obstack-ptr} for allocation of objects.

When all +the objects in a chunk become free, the obstack library automatically +frees the chunk (@pxref{Preparing for Obstacks}). Then other +obstacks, or non-obstack allocation, can reuse the space of the chunk. + +@node Obstack Functions +@section Obstack Functions and Macros +@cindex macros + +The interfaces for using obstacks may be defined either as functions or +as macros, depending on the compiler. The obstack facility works with +all C compilers, including both @w{ISO C} and traditional C, but there are +precautions you must take if you plan to use compilers other than GNU C. + +If you are using an old-fashioned @w{non-ISO C} compiler, all the obstack +``functions'' are actually defined only as macros. You can call these +macros like functions, but you cannot use them in any other way (for +example, you cannot take their address). + +Calling the macros requires a special precaution: namely, the first +operand (the obstack pointer) may not contain any side effects, because +it may be computed more than once. For example, if you write this: + +@smallexample +obstack_alloc (get_obstack (), 4); +@end smallexample + +@noindent +you will find that @code{get_obstack} may be called several times. +If you use @code{*obstack_list_ptr++} as the obstack pointer argument, +you will get very strange results since the incrementation may occur +several times. + +In @w{ISO C}, each function has both a macro definition and a function +definition. The function definition is used if you take the address of the +function without calling it. An ordinary call uses the macro definition by +default, but you can request the function definition instead by writing the +function name in parentheses, as shown here: + +@smallexample +char *x; +void *(*funcp) (); +/* @r{Use the macro}. */ +x = (char *) obstack_alloc (obptr, size); +/* @r{Call the function}. */ +x = (char *) (obstack_alloc) (obptr, size); +/* @r{Take the address of the function}. */ +funcp = obstack_alloc; +@end smallexample + +@noindent +This is the same situation that exists in @w{ISO C} for the standard library +functions. @xref{Macro Definitions, , , libc, The GNU C Library Reference Manual}. + +@strong{Warning:} When you do use the macros, you must observe the +precaution of avoiding side effects in the first operand, even in @w{ISO C}. + +If you use the GNU C compiler, this precaution is not necessary, because +various language extensions in GNU C permit defining the macros so as to +compute each argument only once. + +@node Growing Objects +@section Growing Objects +@cindex growing objects (in obstacks) +@cindex changing the size of a block (obstacks) + +Because memory in obstack chunks is used sequentially, it is possible to +build up an object step by step, adding one or more bytes at a time to the +end of the object. With this technique, you do not need to know how much +data you will put in the object until you come to the end of it. We call +this the technique of @dfn{growing objects}. The special functions +for adding data to the growing object are described in this section. + +You don't need to do anything special when you start to grow an object. +Using one of the functions to add data to the object automatically +starts it. However, it is necessary to say explicitly when the object is +finished. This is done with the function @code{obstack_finish}. + +The actual address of the object thus built up is not known until the +object is finished. Until then, it always remains possible that you will +add so much data that the object must be copied into a new chunk. + +While the obstack is in use for a growing object, you cannot use it for +ordinary allocation of another object.

Regardless of the specified size, longer chunks +will be allocated when necessary for long objects. + +The obstack library allocates chunks by calling the function +@code{obstack_chunk_alloc}, which you must define. When a chunk is no +longer needed because you have freed all the objects in it, the obstack +library frees the chunk by calling @code{obstack_chunk_free}, which you +must also define. + +These two must be defined (as macros) or declared (as functions) in each +source file that uses @code{obstack_init} (@pxref{Creating Obstacks}). +Most often they are defined as macros like this: + +@smallexample +#define obstack_chunk_alloc malloc +#define obstack_chunk_free free +@end smallexample + +Note that these are simple macros (no arguments).

If the @var{tempbase} parameter +to @code{pex_init} was not @code{NULL}, then the output file name is +the concatenation of @var{tempbase} and @var{outname}. If +@var{tempbase} was @code{NULL}, then the output file name is a random +file name ending in @var{outname}. + +@item +@code{PEX_SUFFIX} was not set in @var{flags}. In this +case, if @var{outname} is not @code{NULL}, it is used as the output +file name. If @var{outname} is @code{NULL}, and @var{tempbase} was +not NULL, the output file name is randomly chosen using +@var{tempbase}. Otherwise the output file name is chosen completely +at random. +@end enumerate + +@var{errname} is the file name to use for standard error output. If +it is @code{NULL}, standard error is the same as the caller's. +Otherwise, standard error is written to the named file. + +On an error return, the code sets @code{*@var{err}} to an @code{errno} +value, or to 0 if there is no relevant @code{errno}. + +@end deftypefn + +@deftypefn Extension {const char *} pex_run_in_environment (struct pex_obj *@var{obj}, @ + int @var{flags}, const char *@var{executable}, char * const *@var{argv}, @ + char * const *@var{env}, int @var{env_size}, const char *@var{outname}, @ + const char *@var{errname}, int *@var{err}) + +Execute one program in a pipeline, permitting the environment for the +program to be specified.

In addition to the standard + rand()/srand() like interface, this package also has a special state info + interface. The initstate() routine is called with a seed, an array of + bytes, and a count of how many bytes are being passed in; this array is + then initialized to contain information for random number generation with + that much state information. Good sizes for the amount of state + information are 32, 64, 128, and 256 bytes. The state can be switched by + calling the setstate() function with the same array as was initiallized + with initstate(). By default, the package runs with 128 bytes of state + information and generates far better random numbers than a linear + congruential generator. If the amount of state information is less than + 32 bytes, a simple linear congruential R.N.G. is used. Internally, the + state information is treated as an array of longs; the zeroeth element of + the array is the type of R.N.G. being used (small integer); the remainder + of the array is the state information for the R.N.G. Thus, 32 bytes of + state information will give 7 longs worth of state information, which will + allow a degree seven polynomial. (Note: The zeroeth word of state + information also has some other information stored in it; see setstate + for details). The random number generation technique is a linear feedback + shift register approach, employing trinomials (since there are fewer terms + to sum up that way). In this approach, the least significant bit of all + the numbers in the state table will act as a linear feedback shift register, + and will have period 2^deg - 1 (where deg is the degree of the polynomial + being used, assuming that the polynomial is irreducible and primitive). + The higher order bits will have longer periods, since their values are + also influenced by pseudo-random carries out of the lower bits.
