the connection
the handle type that was passed to tp_connection_request_handles()
the n_handles handles corresponding to ids, in the same order, or %NULL on failure
a copy of the array of n_handles IDs that was passed to tp_connection_request_handles() on success, or %NULL on failure
%NULL on success, or an error on failure
the same object that was passed to tp_connection_request_handles()
Signature of the callback called when tp_connection_request_handles() succeeds or fails.
On success, the caller has a reference to each handle in
handles.Since telepathy-glib version 0.13.8, the handles will remain valid until
connectionbecomes invalid (signalled by #TpProxy::invalidated). In earlier versions, they could be released with tp_connection_unref_handles().For convenience, the handle type and IDs requested by the caller are passed through to this callback, so the caller does not have to include them in
user_data.
