IEnumConnectionPoints Interface

IID_IEnumConnectionPoints

{B196B285-BAB4-101A-B69C-00AA00341D07}

This interface enumerates the current connections for a connectable object. Connectable objects support the following features:

• Outgoing interfaces, such as event sets

• The ability to enumerate the IIDs of the outgoing interfaces

• The ability to connect and disconnect sinks to the object for those outgoing IIDs

• The ability to enumerate the connections that exist to a particular outgoing interface

Use the IEnumConnectionPoints interface to enumerate all the supported connection points for each outgoing IID.
