SIGSETMASK(2)		    BSD	System Calls Manual		 SIGSETMASK(2)

NAME
     sigsetmask	-- set current signal mask

LIBRARY
     Standard C	Library	(libc, -lc)

SYNOPSIS
     #include <signal.h>

     int
     sigsetmask(int mask);

     sigmask(signum);

DESCRIPTION
     This interface is made obsolete by: sigprocmask(2).

     Sigsetmask() sets the current signal mask.	 Signals are blocked from de-
     livery 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 or SIGSTOP to	be blocked.

RETURN VALUES
     The previous set of masked	signals	is returned.

SEE ALSO

HISTORY

     cated.
