sigblock(2)							   sigblock(2)

NAME
       sigblock	 -  Provide a compatibility interface to the sigprocmask func‐
       tion

SYNOPSIS
       int sigblock(
	       int mask );

PARAMETERS
       Specifies the signals to be added to the set of signals currently being
       blocked from delivery.

DESCRIPTION
       The sigblock() function causes the signals specified by the mask param‐
       eter to be added to the set of signals  currently  being	 blocked  from
       delivery.  The signals are blocked from delivery by logically ORing the
       mask value into the signal mask of the process. Signal i is blocked  if
       the  i-th  bit in the mask parameter is a value of 1. Only signals with
       values 1-31 can be masked with the sigblock() function.

NOTES
       It is not possible to block SIGKILL. The system provides no  indication
       of this restriction.

       The  sigblock()	function is provided for compatibility with other UNIX
       systems. It provides a subset of the operations provided	 by  the  sig‐
       procmask() function.

RETURN VALUES
       On completion, the previous set of masked signals is returned.
