SIGSETOPS(3) Linux Programmer's Manual SIGSETOPS(3)NAME
sigemptyset, sigfillset, sigaddset, sigdelset, sigismember - POSIX signal set operations.
SYNOPSIS
#include <signal.h>
int sigemptyset(sigset_t *set);
int sigfillset(sigset_t *set);
int sigaddset(sigset_t *set, int signum);
int sigdelset(sigset_t *set, int signum);
int sigismember(const sigset_t *set, int signum);
DESCRIPTION
The sigsetops(3) functions allow the manipulation of POSIX signal sets.
sigemptyset initializes the signal set given by set to empty, with all signals excluded from the set.
sigfillset initializes set to full, including all signals.
sigaddset and sigdelset add and delete respectively signal signum from set.
sigismember tests whether signum is a member of set.
RETURN VALUE
sigemptyset, sigfillset, sigaddset and sigdelset return 0 on success and -1 on error.
sigismember returns 1 if signum is a member of set, 0 if signum is not a member, and -1 on error.
ERRORS
EINVAL sig is not a valid signal.
