sigpending() System Call in Linux
NAME
sigpending - examine pending signalsSYNOPSIS
#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
Tag | Description |
---|---|
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.SEE ALSO
