NAME
       sleep() - suspend execution for interval

SYNOPSIS
DESCRIPTION
       suspends	 the  current process from execution for the number of seconds
       specified by the argument.

       Actual suspension time can be less than that requested for two reasons:

	 ·  Scheduled wakeups occur at fixed 1 second intervals (on  the  sec‐
	    ond, according to an internal clock), and

	 ·  Any caught signal terminates the sleep following execution of that
	    signal's catching routine.

       Suspension time can be an arbitrary amount longer than requested due to
       the  scheduling of other activity in the system.	 The value returned by
       is the "unslept" amount (the requested time  minus  the	time  actually
       slept)  in  case the caller had an alarm set to go off earlier than the
       end of the requested time, or premature arousal due to  another	caught
       signal.

       seconds must be less than 2^31.

APPLICATION USAGE
       If  a is generated for a multithreaded process, it may not be delivered
       to a thread currently in See the sigwait(2) manpage for details.

SEE ALSO
       sigwait(2), signal(5), thread_safety(5).
