sigsetmask(3BSD)     (BSD System Compatibility)     sigsetmask(3BSD)


       NAME
             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 VALUE
             The previous set of masked signals is returned.
