IEnumDVD_XXXX
The DVD-Video API contains a family of interfaces that maintain collections of items. Each collection contains items from one of several structure types. These interfaces provide a consistent way for you to enumerate and copy these collections. These interfaces all have a common naming format: **IEnumDVD_**Structure_Name.
Every structure type that can be enumerated has its own enumeration interface. To use these interfaces, the client asks an object that maintains a collection of items to create an enumerator interface. All enumeration interfaces have exactly the same set of methods and are used in exactly the same way. The table below lists the methods for the **IEnumDVD_**Structure_Name enumeration interfaces in the order the compiler calls them.
| Programming element | Description |
|---|---|
| Next | Retrieves a specified number of items in the enumeration sequence. |
| Skip | Skips over a specified number of items in the enumeration sequence. |
| Reset | Resets the enumeration sequence to the beginning. |
| Clone | Creates another enumerator that contains the same enumeration state as the current one. |
The IDVDEnumDVD_ Structure_Name interfaces, like all COM interfaces, inherit the IUnknown interface methods. The IUnknown interface supports the following three methods:
The following table lists all of the enumeration interfaces that are available in the DVD-Video API.
Remarks
The table below lists all of the available enumeration interfaces. The reference topics for the individual interfaces contain description of how to obtain pointers to the interfaces.

| IEnumDVD_CELL_PIECE | Enumerates a collection of DVD_CELL_PIECE structures. |
| IEnumDVD_TEXT_ITEM | Enumerates a collection of DVD_TEXT_ITEM structures. |
| IEnumDVD_TEXT_LANGUAGE_UNIT | Enumerates a collection of DVD_TEXT_LANGUAGE_UNIT structures. |
