sleep - suspend operation for a specified time
SYNOPSIS
sleep([n])
TYPES
n non-negative real, defaults to 1
return integer or null value
DESCRIPTION
This uses the C-library sleep (if n is integral) or usleep (for
non-integral n) to suspend operation for n seconds. If n is an
integer and the sleep is stopped by an interruption, the number
of seconds remaining is returned.
One kind of use is to slow down output to permit easier reading of
results, as in:
; for (i = 0; i < 100; i++) {
;; print sqrt(i);
;; sleep(1/2);
;; }
The following illustrates what happens if ctrl-C is hit 5 seconds
after the first command:
; print sleep(20)
[Abort level 1]
15

; sleep(1/3);
