Gets the enumerator for the list of GUIDs that represent categories.
Type: IEnumGUID**
When this method returns, contains the address of a pointer to an IEnumGUID interface that specifies a list of GUIDs that represent categories.
Type: HRESULT
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
In the case of the system folder view object, ICategoryProvider::EnumCategories is used to obtain additional categories that are not associated with a column. When the list of category GUIDs is returned through penum, the UI attempts to retrieve the name of each category. That name is then displayed as a category choice. In the case of Windows XP, that choice appears in the folder's Arrange Icons By menu.
