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 calling 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 function for sigpending() which means that information about
pending real-time signals is not correctly returned.
