Detailed Description

An interface that works with IIndexedOpaqueUserData to allow users of a class that provides opaque user data to request a named 'slot' for their data. Generally what happens is that an allocator will expose this interface and the allocated items will expose the interface to access the user data. Users of the allocator can request named slots of user data before allocating the first item and then all items are created with the required amount of user data space.

Public Member Functions
virtual IIndexedOpaqueUserData::UserDataIndex	RequestUserDataSlot (const _tstring &name)=0
	Request a named user data slot and get an index to use in calls to methods on IIndexedOpaqueUserData.
Protected Member Functions
	~IProvideUserData ()
	We never delete instances of this interface; you must manage the lifetime of the class that implements it.
