If you allocated a handle or pointer memory space, you almost always have to unallocated too. There are few exceptions. However, you can mix up the deallocation method. If you allocated handle space, you could deallocated using a pointer if you already have the handle locked (thus saving the step of unlocking it first). Just remember any variable using the original handle will point to an invalid memory location.
