SIGPENDING(2)              Linux Programmer's Manual             SIGPENDING(2)



NAME
       sigpending - examine pending signals

SYNOPSIS
       #include <signal.h>

       int sigpending(sigset_t *set);

DESCRIPTION
       sigpending()  returns the set of signals that are pending for delivery to the call-
       ing thread (i.e., the signals which have been raised while blocked).  The  mask  of
       pending signals is returned in set.

RETURN VALUE
       sigpending() returns 0 on success and -1 on error.

ERRORS
       EFAULT set points to memory which is not a valid part of the process address space.

NOTES
       See sigsetops(3) for details on manipulating signal sets.

CONFORMING TO
       POSIX.1-2001.

BUGS
       In versions of glibc up to and including 2.2.1, there is a bug in the wrapper func-
       tion  for sigpending() which means that information about pending real-time signals
       is not correctly returned.
