After this … NettetThe stdcall calling convention used for the Win32 API itself slightly changes the function return: the called function is responsible for popping the arguments off the stack, but the basic principles are unchanged. The ‘fastcall’ convention passes one or two arguments in registers, rather than on the stack.
