[Opencxx-users] [opencxx] How to change the function return type

[suresh <su...@em...>]

Hi,
I want to change the function return type from double to string. Can
anybody tell me how to accomplish it?

//sample code
Class A {
Public:

  	A(){}
	~A(){}
	double func();

};
double A::func() {
	double d;
	cout<<"func is called"<<endl;
	return d;
}

In this code, I want to change the function return type to char in all
the places i.e. in function declaration and definition. Inside the
function definition, I am able to change it but not the return type.

Any help is welcome.
             - Thanx SureshLalwani.

        ^^^^^^^^^^^^
        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?

Best regards
Grzegorz
