const-ness as template argument

Question

I have two structs:

  // ----- non-const -----
  struct arg_adapter
  {
      EArgType type;  // fmtA, fmtB, ...

      union
      {
        TypeA * valueA;
            


        

Answer 1

Maybe I didn't get it, but why can't you use

Convert(**const** arg_adapter from, arg_adapter to)

Declare a typedef to simplify the job
