hmmm...i hate these warning messages

dis is the list of warnings I get:

G:\n02\ServerDialog.cpp(6) : warning C4518: 'int ' : storage-class or type specifier(s) unexpected here; ignored
G:\n02\ServerDialog.cpp(6) : warning C4230: anachronism used : modifiers/qualifiers interspersed, qualifier ignored
G:\n02\ServerDialog.cpp(8) : warning C4508: 'kailleraSelectServerDialog' : function should return a value; 'void' return type assumed

for my code:

(Toggle Plain Text)

#include "windows.h"
//#include "n02.h"


__stdcall int kailleraSelectServerDialog(HWND parent){

}

why does it ignore type specifier and then complain it doesnot exist? why is the type specifier ignored in the first place? am I doing something wrong?

Thanks in advance

The __stdcall specifier needs to go after the type of the return value.

So you need to have

(Toggle Plain Text)

int __stdcall kailleraSelectServerDialog(HWND parent){

Can't you instead do?:

(Toggle Plain Text)

int WINAPI kailleraSelectServerDialog(HWND parent){

I thought that would decide the right calling convention.

Well, the order was the problem, as The Dark pointed out, and substituting WINAPI does precisely what, given that:

#define WINAPI __stdcall

in visual c++...does __stdcall do more than just calling convention for the function? Some guy has his dll protos declared as:

(Toggle Plain Text)

__declspec(dllexport) WINAPI kailleraModifyPlayValues(void *values, int size);
//is the same as: 
//__declspec(dllexport) __stdcall kailleraModifyPlayValues(void *values, int size);

And the function is supposed to and does return an integer value.

I think those declarations are just missing the return type, so it is assumed to be returning an int. This would probably only work when you are compiling a C file, rather than a C++ file. Otherwise Visual Studio 8 puts out the following warning:

error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
