Assembly and C

The method you use depends on the compiler, assembler, and linker that you are using, but one thing you''ll most likely have to do in any case is prefix all your functions defined in assembler with a leading underscore, so instead of calling the function dowhatever you would have to call it _dowhatever in the assembly files (because C prefixes functions with a _ ).

Thanks. I''m using MASM and VC 6.

Well, if I remeber correctly all you have to do in that case is just add your .asm file to the project normally and it will be assembled and linked in with the rest of the files to make the exe, assuming VS is configured properly (I don''t remeber having to do anything special to get assembly to work, but it''s been a long time since I''ve used asm, so I could have forgotten something)

I think you will also need to use extern "c" to prevent name mangling for C+. I believe in TASM there is a macro to generate mangled names so there might be a similar macro in MASM. Even so it will still be implementation dependant and extern "c" would be the correct way to go. As far as the receiving end, i.e. calling assembler routines, it is up to your assembler program to use the stack correctly. Easiest is just to look at what the compiler generates for calls to c/c++ routines and what happens once you are in them.
