-Name            sleep - suspends execution for interval
-
-Usage           unsigned sleep(unsigned seconds);
-
-Prototype in    dos.h
-
-Description     With a call to sleep, the current program is
-                suspended from execution for the number of seconds specified
-                by the argument seconds. The interval is only accurate to
-                the nearest hundredth of a second, or the accuracy of the
-                MS-DOS clock, whichever is less accurate.
-
