19 sd_bus_reply_method_return() sends a reply to the call message. The
20 type string types and the arguments that follow it must adhere to the
21 format described in sd_bus_message_append(3). If no reply is expected
22 to call, this function succeeds without sending a reply.
23
25 On success, this function returns a non-negative integer. On failure,
26 it returns a negative errno-style error code.
