1). Just use the Fluid Studio! Why do you want to write your own memory tracking code when Fluid Studio's version has been around a while, and has been tested very well? In case you only saw the old FlipCode article.... the complete source code to the mem manager is found here: http://www.fluidstudios.com/pub/FluidStudios/MemoryManagers/Fluid_Studios_Memory_Manager.zip. I have used this is many projects. Include the header into all your source files, and it will print you out nice .txt reports of all the memory leaks in your application.

Instead of taking this approach, go with a base Object class. All your classes can be derived from a base object class. This can be used to assign unique ids to all objects in your app, as well as handle memory management in a central location (it can declare it's own "new" declaration that is inherited by all subclasses).
struct BaseObject{ BaseObject() {}; virtual ~BaseObject() {}; static void *operator new (size_t size) { int i = 0; void *p = malloc( size ); return p; } static void operator delete (void *p) {}};class AnotherChildObject : public BaseObject{public: AnotherChildObject() {}; virtual ~AnotherChildObject() {};};class ChildObject : public BaseObject{public: ChildObject() { AnotherChildObject *aco = new AnotherChildObject(); } virtual ~ChildObject() {};};int main(int argc, _TCHAR* argv[]){ ChildObject *co = new ChildObject(); return 0;}Quote:Original post by Doggan

...is what I meant. All the 'news' here reference the same function. If all the objects you create with new are derived from this BaseObject, you have a centralized location to track all your memory allocations from.
