sigsetmask(3-BSD) MISC. REFERENCE MANUAL PAGES  sigsetmask(3-BSD)



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  pro-
     vided 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.
