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


   NAME
         sigsetmask - set current signal mask

   SYNOPSIS
         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.
