Howto retrieve a member function's address?
Author
I''m writing a function pointer that can deal with any number of arguments as well as any calling convention (which includes __thiscall), while it is important that every such pointer is of the same type, i.e. that the class is not templatized. Casting, for whatever reason, does not work (not even reinterpret_cast), so I thought I''ll try to cheat with ASM, like so:
I''m aware that I would have to clone this function for every number of arguments a member function might have, but I could live with that. Does anyone know how to fix the above code?
Another way of getting to know a member function''s address (it is in memory only once (hence the "this" pointer) so it must be possible) would of course be as much appreciated.
Thanks in advance.
You don''t have to reinvent the wheel, use boost::function, it does what you want and can easily be combined with boost::bind for endless hours of coding fun.
