SIGSETMASK(2)                 System Calls Manual                SIGSETMASK(2)



NAME
       sigsetmask - set current signal mask

SYNOPSIS
       #include <&lt;signal.h>&gt;

       int sigsetmask(mask)
       int mask;

DESCRIPTION
       sigsetmask()  sets  the  set  of  signals  currently being blocked from
       delivery according to mask.  A signal is blocked if the appropriate bit
       in  mask  is  set.   The macro sigblock(2) is provided to construct the
       mask for a given signum.

       The system silently disallows blocking SIGKILL and SIGSTOP.

RETURN VALUES
       sigsetmask() returns the previous signal mask.
