From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- libiberty/sigsetmask.c | 40 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 40 insertions(+) create mode 100644 libiberty/sigsetmask.c (limited to 'libiberty/sigsetmask.c') diff --git a/libiberty/sigsetmask.c b/libiberty/sigsetmask.c new file mode 100644 index 000000000..3b708b16a --- /dev/null +++ b/libiberty/sigsetmask.c @@ -0,0 +1,40 @@ +/* Version of sigsetmask.c + Written by Steve Chamberlain (sac@cygnus.com). + Contributed by Cygnus Support. + This file is in the public doamin. */ + +/* + +@deftypefn Supplemental int sigsetmask (int @var{set}) + +Sets the signal mask to the one provided in @var{set} and returns +the old mask (which, for libiberty's implementation, will always +be the value @code{1}). + +@end deftypefn + +*/ + +#define _POSIX_SOURCE +#include +/* Including seems to be needed by ISC. */ +#include +#include + +extern void abort (void) ATTRIBUTE_NORETURN; + +#ifdef SIG_SETMASK +int +sigsetmask (int set) +{ + sigset_t new_sig; + sigset_t old_sig; + + sigemptyset (&new_sig); + if (set != 0) { + abort(); /* FIXME, we don't know how to translate old mask to new */ + } + sigprocmask(SIG_SETMASK, &new_sig, &old_sig); + return 1; /* FIXME, we always return 1 as old value. */ +} +#endif -- cgit v1.2.3
