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.
