NAME
sigsetmask - set current signal mask
SYNOPSIS
#include <signal.h>
sigsetmask(mask);
int mask;
mask = sigmask(signum)
DESCRIPTION
Sigsetmask
sets the current signal mask (those signals
that are blocked from delivery).
Signals are blocked if the
corresponding bit in
mask
is a 1; the macro
sigmask
is provided to construct the mask for a given
signum.
The system
quietly disallows SIGKILL, SIGSTOP, or SIGCONT to
be blocked.
RETURN VALUE
The previous set of masked signals is returned.
