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
