SLEEP(3)		   Linux Programmer's Manual		      SLEEP(3)

NAME
       sleep - sleep for the specified number of seconds

SYNOPSIS
       #include	<unistd.h>

       unsigned	int sleep(unsigned int seconds);

DESCRIPTION
       sleep()	makes  the  calling  thread  sleep  until seconds seconds have
       elapsed or a signal arrives which is not	ignored.

RETURN VALUE
       Zero if the requested time has elapsed, or the number of	 seconds  left
       to sleep, if the	call was interrupted by	a signal handler.

CONFORMING TO
       POSIX.1-2001.

BUGS
       sleep()	may be implemented using SIGALRM; mixing calls to alarm(2) and
       sleep() is a bad	idea.

       Using longjmp(3)	from a signal handler or  modifying  the  handling  of
       SIGALRM while sleeping will cause undefined results.

SEE ALSO
       alarm(2), nanosleep(2), signal(2), signal(7)
