Thread: macros

Hi all,

A quick question on macros. I dont think we came have a same macro defined twice with the an argument different between them. Like for example

Code:

#define DBG( FunPtr, MSG ) dbg(FunPtr, __FUNCTION__, MSG )
#define DBGvARG( FunPtr, MSG, ARG ) dbg(FunPtr, __FUNCTION__, MSG, ARG )

As you could see, if had to define with two different identifiers. It would be good to have a same name and the compiler to decide which one to resolve. Like function overloading in C++.

Something like follow

Code:

#define DBG( FunPtr, MSG ) dbg(FunPtr, __FUNCTION__, MSG )
#define DBG( FunPtr, MSG, ARG ) dbg(FunPtr, __FUNCTION__, MSG, ARG )

Is it possible in C?

Thanks guys!

Nope, can't overload macros. You can make macros that take a variable number of arguments though.

I guess that would solve my problem tho :P
