Variadic Macros : how to solve "too many actual parameters for macro.."

Ive been working on getting some of my code originally built on the mac to run under Visual Studio 2008 Express and have run into a weird problem with the variadic macros i use for my assert code :

The macro is defined as :

#define SH_ASSERT( assertID, exp, description,开发者_StackOverflow中文版 ... ) shAssertBasic( int(exp), assertID, description, __LINE__, __FILE__ , ##__VA_ARGS__ ) 

This all works fine under gcc (under osx) and used to run under VS 2005 however with 2008 I get the following warning :

 warning C4002: too many actual parameters for macro 'SH_ASSERT'

The calling code is simply :

SH_ASSERT(0, donkeys != aliens , "Donkeys are Aliens Code : Code %d condition %d" , 55, 666);

I'm sure Im missing something simple and my google foo is failing me...

Thanks.

Change the argument order (put description with the ... part) to do something like this:

#define SH_ASSERT( assertID, exp, ... ) shAssertBasic( int(exp), assertID, __LINE__, __FILE__, __VA_ARGS__ )

It should do the trick, You also have the possibility to suppress the warning in windows:

#pragma warning (push)
#pragma warning( disable:code/number )
#pragma warning (pop)
