That is, it handles connecting, authentication, and message processing. It should be called in a loop until no further progress can be made or an error occurs. Once no further progress can be made, sd_bus_wait3 should be called. Alternatively the user can wait for incoming data on the file descriptor returned by sd_bus_get_fd3. sd_bus_process processes at most one incoming message per call. If the parameter r is not NULL and the call processed a message, *r is set to this message. The caller owns a reference to this message and should call sd_bus_message_unref3 when the message is no longer needed. If r is not NULL, progress was made, but no message was processed, *r is set to NULL. If progress was made, a positive integer is returned. If no progress was made, 0 is returned. If an error occurs, a negative errno-style error code is returned. systemd1, sd-bus3,
