SIGBLOCK(2)									      SIGBLOCK(2)

NAME
       sigblock - block signals

SYNOPSIS
       #include <signal.h>

       omask = sigblock(mask);
       long omask, mask;

       mask = sigmask(signum)
       long mask;
       int signum;

DESCRIPTION
       Sigblock  causes the signals specified in mask to be added to the set of signals currently
       being blocked from delivery.  Signals are blocked if the corresponding bit in mask is a 1;
       the macro sigmask is provided to construct the mask for a given signum.

       It  is  not  possible to block SIGKILL, SIGSTOP, or SIGCONT;  this restriction is silently
       imposed by the system.

RETURN VALUE
       The previous set of masked signals is returned.
