SLEEP(3)                   Library Functions Manual                   SLEEP(3)



NAME
       sleep - suspend execution for interval

SYNOPSIS
       sleep(seconds)
       unsigned seconds;

DESCRIPTION
       The  current process is suspended from execution for the number of sec-
       onds specified by the argument.  The actual suspension time may  be  up
       to  1  second less than that requested, because scheduled wakeups occur
       at fixed 1-second intervals, and an arbitrary amount longer because  of
       other activity in the system.

       The routine is implemented by setting an alarm clock signal and pausing
       until it occurs.  The previous  state  of  this  signal  is  saved  and
       restored.   If the sleep time exceeds the time to the alarm signal, the
       process sleeps only until the signal would have occurred, and the  sig-
       nal is sent 1 second later.
