INT 2F - MS Windows - VMD - GET 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.

So called because nearly all of the Windows 3.0 drivers had names of the form "VdeviceD". See also device driver.
