rt_sigpending
SIGPENDING(2) Linux Programmer's Manual SIGPENDING(2)
NAME
sigpending - examine pending signals
SYNOPSIS
#include <signal.h>
int sigpending(sigset_t *set);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
sigpending(): _POSIX_C_SOURCE >= 1 || _XOPEN_SOURCE || _POSIX_SOURCE
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.
CONFORMING TO
POSIX.1-2001.
NOTES
See sigsetops(3) for details on manipulating signal sets.
The set of signals that is pending for a thread is the union of the set of signals that is pending for that thread and the set of signals
that is pending for the process as a whole; see signal(7).
A child created via fork(2) initially has an empty pending signal set; the pending signal set is preserved across an execve(2).
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.
