Introduction to Library Functions                          SIG(3)

NAME
     sig - signal interface routines

SYNOPSIS
     #include <ast.h> #include <sig.h>

     int sigunblock(int sig); int sigcritical(int op);

DESCRIPTION
     sigunblock is called to unblocks the signal sig from  within
     a handler currently servicing sig.

     sigcritical controls  a  critical  region  for  the  SIGINT,
     SIGQUIT and SIGHUP signals.  op > 0 pushes the region, op ==
     0 pops the region, and op < 0 returns non-zero if  any  sig-
     nals  are being held in the current critical region.  Signal
     critical regions may be nested.  The current critical region
     level is returned, -1 on error.
