sigsetmask(3)           (BSD Compatibility Package)           sigsetmask(3)

NAME
     sigsetmask - set current signal mask

SYNOPSIS
     /usr/ucb/cc [flag ...] file ... -lucb

     #include <signal.h>

     sigsetmask(mask)
     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 VALUE
     The previous set of masked signals is returned.

     signal(3-ucb), signal(5).
