@ -19,13 +19,11 @@ unsigned int sleep(unsigned int \fIseconds\fP)
The current process is suspended from execution for the number
of seconds specified by the argument.
.PP
The routine is implemented by setting an alarm timer
and pausing until it occurs.
The previous state of this timer is saved and restored.
If the sleep time exceeds the time to the expiration of the
previous timer,
the process sleeps only until the signal would have occurred, and the
signal is sent 1 second later.
The routine is implemented using the 'select' function, so it does not
interfere with alarm timers. If a signal is received, the function returns.
.SH "RETURN VALUE
The amount of time that remains to be slept is returned. This value is
specified in seconds and rounded up.
