Thread: How know smth is a pointer to an object instead of an object?

If there's a define macro that takes an object, how can it figure out if the object passed is the actual object or a pointer to the object?

Pseudo code:

Code:

#define handleTest( obj )                                             \
     Test* t;                                                         \
                                                                      \
     /* want to do something like this */                             \
     if ( obj isOfType pointer ) t = dynamic_cast<Test*> obj;         \
     else t = &( ( Test ) obj );
