Windows nanosleep

windows_nanosleep.c

#include <windows.h>	/* WinAPI */

/* Windows sleep in 100ns units */
BOOLEAN nanosleep(LONGLONG ns){
	/* Declarations */
	HANDLE timer;	/* Timer handle */
	LARGE_INTEGER li;	/* Time defintion */
	/* Create timer */

For Windows versions 2004 and after, use CREATE_WAITABLE_TIMER_HIGH_RESOLUTION. See Windows Timer Resolution: The Great Rule Change
