External asm in c

[ChimpFace9000]

This could go in either the c or asm forum, but i choose c cuz more people visit it. This is also c specific, not C++. How do i write external assembly code to be used in C? I found one tutorial but it was tasm specific, and it also didnt work. So i need to know how to do it in just standard assembly, not tasm specific. Thanks.

Basically, you need to have your procedure defined, and you need to know what calling convention you're using (how the parameters are passed). You can find that by looking at an assembly listing of a small compiled C program.

For the __cdecl calling convention, you need to decorate the name in your asm with "_name" (so just prepend the "_").

Then make a header, and link with the .obj file.

The link doesnt work. But for the most part ive got it figured out. For some reason though, nothing will work when i start using virtual screens and having to pass the address as one of the variables.
