sigsetmask --
(BSD) set current signal mask
Synopsis
/usr/ucb/cc [flag . . . ] file . . .
#include <signal.h>
sigsetmask(int mask);
#define 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
from being blocked.
Return values
The previous set of masked signals is returned.
