    data types types...

    im pretty new to this kind of C++ and i was wondering if there is a way to determine what is the type of a pointer. say i got a void* that points to an int. how can i detect that? or pass an int* to a void* accepting function, then identifying its type.(e.g: without overloading...).

    any help?

    You don't. Keep the original pointer type. Overload the function or make it a template.

    If there is no alternative whatsoever (e.g. you have a void * from a callback function) you just need to make sure you know the real type of the pointer. Pass only a single type of pointer in to it.
