INT 2F - OS/2 - GET VDD 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. ENTRY POINT
	AX = 4011h
	DS:(E)SI -> ASCIZA NUL-terminated ASCII string.	The ASCIZ string "ABC" consists of the four bytes 41h, 42h, 43h, and 00h.  Unless otherwise specified, maximum lengths given in the interrupt list do not include the terminating NUL. name of VDD registered with VDHRegisterAPI
Return: ES:DI -> breakpoint address to call for VDD 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., or 0000h:0000h
Note:	this function may be invoked from either V86see Virtual-86 Mode or protected mode, and
	  will return the appropriate address to call for invoking the VDD
	  in that mode
