Description
Unregisters a client channel callback.
The UnregisterChannelCallback method unregisters a channel callback with a given name specified by the ChannelName parameter. UnregisterChannelCallback has two overloads. Call the first overload with the ChannelName, ClientId, and Owner parameters. The second overload must be called with the ChannelName, ClientId, and CallbackId parameters. The second overload unregisters a client callback and no notifications or broadcasts are possible after unregistering the client callback.
ChannelName represents the name of the channel callback.
ClientId specifies the identifier of the client channel.
CallbackId specifies the identifier of the channel callback.
Owner specifies whether the callback's items are freed(True) or deleted (False).
