pause

Purpose

     Suspends a process until a signal is received.

Syntax

     int pause ( )

Description

     The pause system call  suspends the calling process until
     it receives a signal.  The signal must not be one that is
     ignored by  the calling  process.  pause does  not affect
     the action taken upon the receipt of a signal.

     If the signal received causes the calling process to ter-
     minate, then the pause system call does not return.

     If  the  signal is  caught  by  the calling  process  and
     control  is returned  from the  signal-catching function,
     then the calling process resumes execution from the point
     of suspension; the  pause system call returns  a value of
     -1  and  sets errno  to  EINTR.   (For information  about
     signal-catching functions, see "signal.")
