- PCMsgTst Build Instructions
- 8/29/96
-
- PCMsgTst is built from some C code as well as some x86 assembler code. The x86
- assembler code is used for accessing the messaging system through the INT 5Fh
- interface. Also, because the messaging system is still 16-bit based, getting
- data in and out of some of the registers is easier this way. Although, it is
- possible that some of this could be done from in-line assembly within C
- functions.
-
- The msg.asm and msg.inc files were compiled with the ml tool from MASM v6.11.
- Executing the BLDMSG.BAT file will execute the ml tool with the proper flags
- set. In the meantime, the msg.obj file is included as it needs to link with
- PCMsgTst tool when PCMsgTst.C is built.
-
- To build PCMsgTst, we used MSVC v1.5. Why such an old version, you may ask?
- Well, you need to be able to generate 16-bit code to interact with the
- message system. So a 32-bit compiler won't work. The PCMsgTst.MAK file
- (generated by MSVC 1.5) will build the tool and include the Msg.obj file
- needed at link time.
