sigfillset()

initialize signal set to contain all signals 

Function

SYNOPSIS

#include <signal.h>

int sigfillset(sigset_t *set);

DESCRIPTION

The sigfillset() function manipulates sets of signals. It operates on data objects that the application addresses. It does not operate on any set of signals known to the system (such as the set blocked from delivery to a process or the set pending for a process).

sigfillset() initializes the signal set that set points to include all signals that the system defines.

Applications call either sigfillset() or sigemptyset() at least once for each object of type sigset_t prior to any other use of that object. If such an object is not initialized in this way, the results are not defined.

PARAMETERS

set 

Points to a signal set.

RETURN VALUES

If successful, sigfillset() returns a value of zero. On failure, it returns -1 and sets errno to one of the following values:

MULTITHREAD SAFETY LEVEL
