Pointer to a string containing the name of the object. For more information, see CBaseObject.
Pointer to the owner of this object. If the object is aggregated, pass a pointer to the aggregating object's IUnknown interface. Otherwise, set this parameter to NULL.
Pointer to an HRESULT value. Ignored.
Pointer to a CCritSec object. In your derived class, declare a CCritSec member variable and use the address of it for this parameter.

Whenever you access those variables in your derived class, hold this lock.
