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

NAME
     sleep - suspend execution for some seconds

SYNTAX
     sleep(seconds)
     unsigned seconds;

DESCRIPTION
     The current process is suspended 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 an arbitrary amount longer because of other
     activity in the system.

     The routine is implemented by setting an alarm clock signal
     and pausing until it occurs.  The previous state of this
     signal is saved and restored.  If the sleep time exceeds the
     time to the alarm signal, the process sleeps only until the
     signal would have occurred, and the signal is sent 1 second
     later.
