sleep(3BSD)          (BSD System Compatibility)          sleep(3BSD)


       NAME
             sleep - (BSD) suspend execution for interval

       SYNOPSIS
             /usr/ucb/cc [flag . . . ] file . . .
             sleep(unsigned seconds);

       DESCRIPTION
             sleep suspends the current process from execution for the
             number of seconds specified by the argument.  The actual
             suspension time may be up to 1 second less than that
             requested, because scheduled wakeups occur at fixed 1-second
             intervals, and may be an arbitrary amount longer because of
             other activity in the system.

             sleep is implemented by setting an interval timer and pausing
             until it expires.  The previous state of this timer is saved
             and restored.  If the sleep time exceeds the time to the
             expiration of the previous value of the timer, the process
             sleeps only until the timer would have expired, and the signal
             which occurs with the expiration of the timer is sent one
             second later.
