INT 21,44,B / IOCTL,B - Set Sharing Retry Count



	AH = 44h
	AL = 0B
	CX = pause between retries  (default 1)
	DX = number of retries	(default 3)


	on return
	AX = error code if CF set  (see DOS ERROR CODES)


	- retry parameters are associated with file locking
	- differences in CPU and clock speeds affect length of pauses
	- requires SHARE be loaded or invalid function is returned
	- implemented from DOS 3.0
