Abstract:
|
|
|
|
This is the header file supporting third party bops.
|
|
isvbop.inc is the inc file for this h file.
|
|
|
|
Note:
|
|
Following include file uses 'DB' to define assembly macros. Some
|
|
assemblers use 'emit' instead. If you are using such a compiler,
|
|
you will have to change db's to emit's.

/** RegisterModule - This Bop call is made from the 16 bit module
|
|
* to register a third party DLL with the bop
|
|
* manager. This call returns a handle to the
|
|
* 16bit caller which is to be used later to
|
|
* dispatch a call to the DLL.
|
|
*
|
|
* INPUT:
|
|
* Client DS:SI - asciiz string of DLL name.
|
|
* Client ES:DI - asciiz string of Init Routine in the DLL. (Optional)
|
|
* Client DS:BX - asciiz string to Dispatch routine in the DLL.
|
|
*
|
|
* OUTPUT:
|
|
* SUCCESS:
|
|
* Client Carry Clear
|
|
* Client AX = Handle (non Zero)
|
|
* FAILURE:
|
|
* Client Carry Set
|
|
* Client AX = Error Code
|
|
* AX = 1 - DLL not found
|
|
* AX = 2 - Dispacth routine not found.
|
|
* AX = 3 - Init Routine Not Found
|
|
* AX = 4 - Insufficient Memory
|
|
*
|
|
* NOTES:
|
|
* RegisterModule results in loading the DLL (specified in DS:SI).
|
|
* Its Init routine (specified in ES:DI) is called. Its Dispatch
|
|
* routine (specified in DS:BX) is stored away and all the calls
|
|
* made from DispatchCall are dispacthed to this routine.
|
|
* If ES and DI both are null than the caller did'nt supply the init
|
|
* routine.
