Variable name from macro argument

Question

I'd like to do something like this:

class SomeClass { };  GENERATE_FUNTION(SomeClass) 

The GENERATE_FUNCTION macro I'd like to define a function whose name is to be determined by the macro argument. In this case, I'd like it to define a function func_SomeClass. How can that be done?

Answer 1

#define GENERATE_FUNCTION(Argument) void func_##Argument(){ ... }
