замена __VA_ARGS__

[Admin]

Возможно ли на Visual C+ заменить данную конструкцию

__VA_ARGS__

тоесть релаизовать примерно следующее

#define debug_printf(...)   define_strace (DEBUG, __VA_ARGS__)

Надо переслать в макрос произвольно количество параметров

[Admin]

одно из решений что я нешел писать все аргументы в скобке

Have you tried:

#define MyErrorBox(params) (line = __LINE__, file = __FILE__,
MyErrorBoxInternal(params))


The problem is of course that you have to write:


MyErrorBox((hWnd,text,caption,­flags))


instead of
MyErrorBox(hWnd,text,caption,f­lags)


Another way is to wait for Visual C++ to catch up with C9X and allow for
VA_ARGS in macros:


#define MyErrorBox(...) (line = __LINE__, file = __FILE__, \
MyErrorBoxInternal(__VA_ARGS__­))


Unfortunately we all have to wait a bit for that...Visual C++ 7.x may have it
though.... Until then, try the way above.


Another idea.... Just keep MyErrorBox as a regular function and have a small
simple macro to just set those __LINE__ and __FILE__ values...


int MyErrorBox(int line, const char * file, ...other params...);


#define LF   __LINE__, __FILE__


if (MyErrorBox( LF, .... ) == IDYES)....


int answer = MyErrorBox( LF, ... );
