sleep

sleep(3C)																 sleep(3C)

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:

	 o  Scheduled wakeups occur at fixed 1 second intervals (on the second, according to an internal clock), and

	 o  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).
