Get a pointer to he base of a managed object
the standard custom layer context pointer
the id of the managed object to query
on success, when the object exists, a pointer to the base of the memory allocated for the object, otherwise zero
Managed objects are essentially arrays with special management inside the core, such as markers. This call returns a pointer to base of the array. Careful! This pointer is a pointer to memory tied to a managed scope, so it can lose validity if the scope closes, and modifications to the memory at this pointer will be reflected throughout all systems relying on it.
