INT 7D - HyperPAD v2.2 - 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. ACCESS
Note:	this vector is hooked but immediately passed on (without checking
	  whether the previous handler was 0000h:0000h).  The sole purpose of
	  this vector is to provide the address of the data area described
	  below (see #03862).


Format of HyperPAD data area:
Offset	Size	Description	(Table 03862)
 -16h	DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address.	pointer to ??? FAR function
 -12h	DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address.	pointer to callback setting function
		[C calling conventions, (*callback)(int (_loadds far *)()) ]
 -0Eh 6 BYTEs	signature "BRC001"
 -08h	DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address.	pointer to previous INT 7D handler
 -04h	DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address.	pointer to ??? data
 00h		HyperPAD INT 7D handler
