Most compilers support an option to output the result of
preprocessing. RTFM and see if yours does as well. Then
use your macro and see what it expands into.

Rewrite it as an inline function.

With all due respect, declarations cannot be rewritten as
inline functions.

Did you read the OP's example Victor?

Yes, I did. It contains a declaration.

So it does. That'll teach me to post before breakfast!
