Memory allocation inside DLL returning null pointer

Question

I'm using a DLL which performs some memory allocation and returns a pointer. The code is something like that:

ObjectClass *obj = FunctionFromDLL();

obj is a valid pointer but obj->SubObject is a bad pointer (0xcdcdcd) I checked and FunctionFromDLL() correctly allocates SubObject, this pointer only gets a bad value when function is returning to caller.

Is there something special for the DLL to "share" its memory?

Answer 1

There is no special way of sharing memory allocated between dll and app, just make sure to delete memory in dll AFTER you don't use it anymore.
