sleep

Suspends execution for an interval (seconds).

Defined in header <dos.h>

Syntax

#include <dos.h>
void sleep(unsigned seconds);

Remarks

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 DOS clock, whichever is less accurate.

Return value
