INT 2F C - MS Windows - "VMD" VIRTUAL MOUSE DEVICE API(Application Program[ming] Interface) The defined set of calls which a program may make to interact with or request services of the operating system or environment under which it is running. Because the inputs and outputs of the calls are well-defined, a program using the API can continue using the identical calls even if the internal organization of the program providing the API changes. AX = 1607h BX = 000Ch (VxDA virtual device driver for Windows 3.x or 95. So called because nearly all of the Windows 3.0 drivers had names of the form "VdeviceD". See also device driver. identifier of "VMD") Return: CX = nonzero if mouse driver already virtualized Note: VMD (Virtual Mouse Driver) calls this and then checks whether CX is nonzero; if yes, it will not automatically virtualize the mouse driver. This would be used if MOUSE.COM already virtualizes itself using the Windows API(Application Program[ming] Interface) The defined set of calls which a program may make to interact with or request services of the operating system or environment under which it is running. Because the inputs and outputs of the calls are well-defined, a program using the API can continue using the identical calls even if the internal organization of the program providing the API changes..
