NAME

       sleep - Suspends execution for an interval of time

LIBRARY

       Standard C Library (libc.a) Threads Library (libpthreads.a)

SYNOPSIS

       #include <unistd.h>

       unsigned int sleep (	 unsigned int seconds );

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       sleep():  XPG4, XPG4-UNIX

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

PARAMETERS

       Specifies the number of seconds to sleep.

DESCRIPTION

       The  sleep()  function  suspends  execution  of	a process for the interval specified by the seconds parameter.	The suspension time may be
       longer than requested due to the scheduling of other activity by the system.

       In a multi-threaded environment, the sleep() function is redefined so that only the calling thread is suspended.

RETURN VALUES

       If the sleep() function returns because the requested time has elapsed, it returns 0 (zero).  If the sleep() function  returns  because	it
       caught a  signal, the function returns the number of seconds remaining in the suspension.
