sleep

sleep(3C)																 sleep(3C)

NAME

       sleep - suspend execution for an interval of time

SYNOPSIS

       #include <unistd.h>

       unsigned int sleep(unsigned int seconds);

       The  caller  is	suspended  from execution for the number of seconds specified by the argument. The actual suspension time may be less than
       that requested because any caught signal will terminate the sleep() following execution of that signal's catching routine.  The	suspension
       time  may  be longer than requested by an arbitrary amount because of the scheduling of other activity in the system. The value returned by
       sleep() will be the ``unslept'' amount (the requested time minus the time actually slept) if the caller incurred premature arousal  because
       of a caught signal.

       The use of the sleep() function has no effect on the action or blockage of any signal. In a multithreaded process, only the invoking thread
       is suspended from execution.
