|
|
// Note: There are three types of IUnknown implementations here. The first
|
|
// is for the "Shared Folders" COM objects. Each of these interfaces can be
|
|
// QueryInterface'd from the others, and all return the same IUnknown. There
|
|
// is a single shared object reference count (not interface reference count).
|
|
// These interfaces include: IShellFolder, IPersistFolder, IRemoteComputer.
|
|
//
|
|
// The second type is standard, separate interfaces that get interface-specific
|
|
// reference counts. This includes: IShellDetails, IEnumIDList,
|
|
// IExtractIcon, IExtractIconA.
|
|
//
|
|
// The third type is the IUnknown implementation for the "Shared Folders"
|
|
// COM object class factory. This object is a global static object, so it
|
|
// never gets destructed.
