sigsetmask(3)      UNIX System V(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.
