Hello,

 

I'm trying to make a macro for the following case (essentially, I have to translate a run-time decision to a compile-time one):

 

switch(i)

{

case 1: my_func(arg, offsetof(my_struct, arr[1].my_field))); break;

}

 

If I could hard-code the whole function call into the macro, I could do something like this:

#define EXPR(unused, x, text) my_func(arg, offsetof(my_struct, arr[x].my_field))); break;

 

#define MY_MACRO(x) \
switch(x)\
{\
BOOST_PP_REPEAT(x, EXPR, _)\
}

 

However, I'd like to pass "arg" and "my_field" as parameters to this macro.

What would be the right way to do this?

 

Thanks.
