Introducing 'the "DJGPP/MinGW/MSVC/GCC on *nix compatible" call asm function
|
|
safely from C/C++' macro function!
|
|
|
|
Usage:
|
|
asm_call( func_name );
|
|
|
|
That's all there is to it!!!
|
|
|
|
Note: This will not work with GCC when using the parameter -MASM=intel
|
|
I'd fix that if anyone knows if that parameter defines something I can check
|
