Macro as a parameter to another macro

Question

I\'m trying to pass the parameters to macro SETBIT with another predefined macro like this:

#define SETBIT(ADDRESS,BIT,N) {(N) ? (ADDRESS &=         


        

Answer 1

Just for the sake of completeness, that same manual you are linking to also states:

The number of arguments you give must match the number of parameters in the macro definition. When the macro is expanded, each use of a parameter in its body is replaced by the tokens of the corresponding argument.

So ooga's example is a nice demonstration of how macro expansion works recursively, first the outer macro gets expanded, then the argument.
