        classA* objA2 ?

Do you want to translate individual header files? It is going to be
difficult, since OpenC++ sits behind preprocessor, so it does not really
see separate header files. If it is enough to just add the macros in
*translation unit*, that should be easy (see AppendAfterTopLevel()).
Remember to instruct OpenC++ to perform second preprocessor pass.
If this advice is not what you are looking for then I am afraid you have
to shed some more light on why do you need those macros.

Because object created with "new" does not have a name. What do you mean
by "object name" in:

    some_function(2, new classA);

?

Do you really want to find all instantiations or just instantiations of
some specific form (e.g. "classA* ID = new classA") and nothing else?
