[ROOT] reference to pointer sent by G__CallFunc

Hi,

I'm trying to call a function known to the interpreter from compiled code.
It works nicely thanks to some examples already given by Masa using the
G__CallFunc class. But I cannot send a reference to object or pointer to
the function. More specifically, my problem is the same as the one
described by Jacek :


        3. I cannot convince G__CallFunc to pass the reference (Double_t& X).
           In case of a pointer "Y" I can simply say "func.SetArg(((long)Y))".
           If I say "func.SetArg(((long)&X))", the function gets the
           reference to somewhere in "para.*", not the original reference
           to "X". This happens in all cases (G__INTERPRETEDFUNC,
           G__BYTECODEFUNC,G__COMPILEDINTERFACEMETHOD) - can I somehow
           convince SetArg to provide the original reference to "X" ?

Does anybody know how to do ?

Cheers

Damir
