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.
 

CONFORMING TO

POSIX.1-2001.  

NOTES

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

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.
