You can use "typeid" operator defined in typeinfo.h for this. check this link : http://en.wikipedia.org/wiki/Typeid

The typeid operator will give an object of std::type_info class, which has a name() function returning char *. Once you get the type in string form, you can identify the pointer easily.

Hope it helps.
