claim_with_async

Called by an approver to claim channels for handling internally.

If this method is called successfully, the process calling this method becomes the handler for the channel.

If successful, this method will cause the invalidated signal to be emitted, in the same way as for handle_with_async.

This method may fail because the dispatch operation has already been completed. Again, see handle_with_async for more details. The approver MUST NOT attempt to interact with the channels further in this case.

This is an improved version of claim_async as it tells client about the new channels being handled.

TP_CHANNEL_DISPATCH_OPERATION_FEATURE_CORE feature must be prepared before calling this function.

Parameters:

this	a ChannelDispatchOperation
client	the BaseClient claiming this
callback	a callback to call when the call returns
user_data	data to pass to callback
