NAME    [Toc]    [Back]

       sleep - Sleep for the specified number of seconds

SYNOPSIS    [Toc]    [Back]

       #include <unistd.h>

       unsigned int sleep(unsigned int seconds);

DESCRIPTION    [Toc]    [Back]

       sleep()	makes  the  current  process  sleep until seconds seconds have
       elapsed or a signal arrives which is not ignored.

RETURN VALUE    [Toc]    [Back]

       Zero if the requested time has elapsed, or the number of  seconds  left
       to sleep.

CONFORMING TO    [Toc]    [Back]


BUGS    [Toc]    [Back]

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

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