- Using `-' as the first character of the list of option characters
- selects this mode of operation.

-/* Scan elements of ARGV (whose length is ARGC) for option characters
- given in OPTSTRING.
-
- If an element of ARGV starts with '-', and is not exactly "-" or "--",
- then it is an option element. The characters of this element
- (aside from the initial '-') are option characters. If `getopt'
- is called repeatedly, it returns successively each of the option characters
- from each of the option elements.
-
- If `getopt' finds another option character, it returns that character,
- updating `optind' and `nextchar' so that the next call to `getopt' can
- resume the scan with the following option character or ARGV-element.
-
- If there are no more option characters, `getopt' returns -1.
- Then `optind' is the index in ARGV of the first ARGV-element
- that is not an option. (The ARGV-elements have been permuted
- so that those that are not options now come last.)
-
- OPTSTRING is a string containing the legitimate option characters.
- If an option character is seen that is not listed in OPTSTRING,
- return '?' after printing an error message. If you set `opterr' to
- zero, the error message is suppressed but we still return '?'.
-
- If a char in OPTSTRING is followed by a colon, that means it wants an arg,
- so the following text in the same ARGV-element, or the text of the following
- ARGV-element, is returned in `optarg'. Two colons mean an option that
- wants an optional arg; if there is text in the current ARGV-element,
- it is returned in `optarg', otherwise `optarg' is set to zero.
-
- If OPTSTRING starts with `-' or `+', it requests different methods of
- handling the non-option ARGV-elements.
- See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
-
- Long-named options begin with `--' instead of `-'.
- Their names may be abbreviated as long as the abbreviation is unique
- or is an exact match for some defined option. If they have an
- argument, it follows the option name in the same ARGV-element, separated
- from the option name by a `=', or else the in next ARGV-element.
- When `getopt' finds a long-named option, it returns 0 if that option's
- `flag' field is nonzero, the value of the option's `val' field
- if the `flag' field is zero.
-
- The elements of ARGV aren't really const, because we permute them.
- But we pretend they're const in the prototype to be compatible
- with other systems.
-
- LONGOPTS is a vector of `struct option' terminated by an
- element containing a name which is zero.
-
- LONGIND returns the index in LONGOPT of the long-named option found.
- It is only valid when a long-named option has been found by the most
- recent call.
-
- If LONG_ONLY is nonzero, '-' as well as '--' can introduce
- long-named options. */

-/* An improved random number generation package. 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. The
- total period of the generator is approximately deg*(2**deg - 1); thus
- doubling the amount of state information has a vast influence on the
- period of the generator. Note: The deg*(2**deg - 1) is an approximation
- only good for large deg, when the period of the shift register is the
- dominant factor. With deg equal to seven, the period is actually much
- longer than the 7*(2**7 - 1) predicted by this formula. */

-/* For each of the currently supported random number generators, we have a
- break value on the amount of state information (you need at least thi
- bytes of state info to support this random number generator), a degree for

- separation between the two lower order coefficients of the trinomial. */

-@var{buf} at most @code{@var{n}-1} bytes of text, followed by a
-terminating null byte, for a total of @var{n} bytes.
-On error the return value is -1, otherwise it returns the number of

-NAME

- init_error_tables -- initialize the name and message tables
-
-SYNOPSIS
-
- static void init_error_tables ();
-
-DESCRIPTION
-
- Using the error_table, which is initialized at compile time, generate
- the error_names and the sys_errlist (if needed) tables, which are
- indexed at runtime by a specific errno value.
-
-BUGS
-
- The initialization of the tables may fail under low memory conditions,
- in which case we don't do anything particularly useful, but we don't
- bomb either. Who knows, it might succeed at a later point if we free
- some memory in the meantime. In any case, the other routines know
- how to deal with lack of a table after trying to initialize it. This
- may or may not be considered to be a bug, that we don't specifically
- warn about this particular failure mode.

-NAME

- init_signal_tables -- initialize the name and message tables
-
-SYNOPSIS
-
- static void init_signal_tables ();
-
-DESCRIPTION
-
- Using the signal_table, which is initialized at compile time, generate
- the signal_names and the sys_siglist (if needed) tables, which are
- indexed at runtime by a specific signal value.
-
-BUGS
-
- The initialization of the tables may fail under low memory conditions,
- in which case we don't do anything particularly useful, but we don't
- bomb either. Who knows, it might succeed at a later point if we free
- some memory in the meantime. In any case, the other routines know
- how to deal with lack of a table after trying to initialize it. This
- may or may not be considered to be a bug, that we don't specifically
- warn about this particular failure mode.

-@deftypefun int strverscmp (const char *@var{s1}, const char *@var{s2})
-The @code{strverscmp} function compares the string @var{s1} against
-@var{s2}, considering them as holding indices/version numbers. Return
-value follows the same conventions as found in the @code{strverscmp}
-function. In fact, if @var{s1} and @var{s2} contain no digits,
-@code{strverscmp} behaves like @code{strcmp}.
-
-Basically, we compare strings normally (character by character), until
-we find a digit in each string - then we enter a special comparison
-mode, where each sequence of digits is taken as a whole. If we reach the
-end of these two parts without noticing a difference, we return to the
-standard comparison mode. There are two types of numeric parts:
-"integral" and "fractional" (those begin with a '0'). The types
-of the numeric parts affect the way we sort them:
-
-@itemize @bullet
-@item
-integral/integral: we compare values as you would expect.
-
-@item
-fractional/integral: the fractional part is less than the integral one.
-Again, no surprise.
-
-@item
-fractional/fractional: the things become a bit more complex.
-If the common prefix contains only leading zeroes, the longest part is less
-than the other one; else the comparison behaves normally.
-@end itemize
-
-@smallexample
-strverscmp ("no digit", "no digit")
- @result{} 0 // @r{same behavior as strcmp.}
-strverscmp ("item#99", "item#100")
- @result{} <0 // @r{same prefix, but 99 < 100.}
-strverscmp ("alpha1", "alpha001")
- @result{} >0 // @r{fractional part inferior to integral one.}
-strverscmp ("part1_f012", "part1_f01")
- @result{} >0 // @r{two fractional parts.}
-strverscmp ("foo.009", "foo.0")
- @result{} <0 // @r{idem, but with leading zeroes only.}
-@end smallexample
-
-This function is especially useful when dealing with filename sorting,
-because filenames frequently hold indices/version numbers.
