__cdecl, __stdcall and __fastcall are all called the exact same way?

Question

I am using Visual C++ 2010, and MASM as my x64-Assembler.
This is my C++ code:

// include directive
#include \"stdafx.h\"
// functions
extern \"C\" int         


        

Answer 1

As far as i know x64 only uses the __fastcall convention. __cdecl and stdcall will just be compiled as __fastcall.
