NAME
       enter_quiet_zone, exit_quiet_zone - Prevent keyboard interruption of program actions (Enhanced Security)

LIBRARY
       Security Library - libsecurity.so

SYNOPSIS
       #include <prot.h>
       void enter_quiet_zone();

       #include <prot.h>
       void exit_quiet_zone();

DESCRIPTION
       The  function  sets  the appropriate signals to a state that prevents keyboard interruption of program actions.	If this function is called
       multiple times without an intervening call, nothing is done.  If an alarm has been set, the time left to go is saved.

       The function restores the signals to their previous state.  Do not call this function from reentrant code because it uses a static area.  A
       pending alarm clock is restored.

       The signals that are affected are SIGHUP, SIGINT, SIGQUIT, SIGSYS, SIGALRM.
