Macros for calling c/c++ functions

[fallenhobbit]

I recently posted a few things on having problems calling c/c++ runtime functions because the c/c++ runtimes use the _cdecl calling convention. This is the culmination of my research thus far. Its a series of macros that let you easily call most of the exported functions in the VC++ msvcrt.dll runtime. Feel free to flame me...Im kinda new to assembly (about a year coding in it)....cheers

Hi fallenhobbit,

Welcome to the forum, nice work :U

You have another choice to declare C functions:

Code Select Expand

printf PROTO C :VARARG

Yes, I was about to suggest the same thing. I guess it's because of the choice to make everything stdcall in MASM32 instead of adding the proper calling conventions to the prototype includes that many people do not consider this.

Here is a version that shows it works with invoke .. I didn't add printf so there's still a bit of work to do ;).

There is an easy method to create an import library for msvcrt.dll

polib /out:msvcrt.lib \windows\system32\msvcrt.dll
