If you want to use that pointer, i.e. call the member function, then you must define it in some way (and you must retrieve the member object too). How you define the function? pointer_type pointer; pointer = someobject.get_pointer( "foobar2" ); What is pointer_type? Once you define pointer_type you can use it in the bimap. A pointer to a member function is still a simple function pointer, this is why you need the member pointer to call it. A member function is nothing more than a normal function with the special *this* pointer assigned to the member object that called the function (and of course the code inside the function use implicitly the this pointers when accessing any member item). With virtual functions the function pointer is not static but stored in the class. Andrea

pointer as the base class for the bimap?
You need two maps (string->pointer and pointer->string), a bimap should do the work. Isn't it possible to cast a function pointer to a generic void
Sorry, this doesn't work. A "pointer to a member function" is _not_ a "function pointer" and not a general (void*) pointer. It's size is bigger than a pointer to a normal function because it stores additional information about the object. I haven't found a conversion between all "pointer to member functions" to something "comparable" like a normal pointer or a number or a string. (Maybe typeinfo helps? Is it portable?)
Take a look at this for the strange objects that member function pointers are:
