casting - HARD

how can i cast a class i made into a void* and back again?

Why do you want to? You very rarely need to cast a pointer to a void*.

um, actually its this other guy who wants to know, i think he's trying to create a new thread but i don't remember which API it was he was using, i don't think it was CreateThread(Ex)

_beginthread[ex]?

In that case just something like:

Code:

---


... threadproc(void *param) {
    myclass *mc = dynamic_cast<myclass*>(param);
}

// ...
myclass mc;

_beginthread(..., &mc, ...);

---

Can't remember any of the threading details right now :p

I think you need a reinterpret_cast, dynamic_cast won't work (works only for casting among class hierarchies with RTTI enabled). I think static_cast for something* to void* and reinterpret_cast for void* to something*.

Clashes of good C++ and C APIs always favor C.

You're right...I'm just too used to using dynamic_cast :D
