NAME¶sd_bus_set_exit_on_disconnect, sd_bus_get_exit_on_disconnect - Control the exit behavior when the bus object disconnects
int sd_bus_set_exit_on_disconnect(sd_bus *bus, int b);
int sd_bus_get_exit_on_disconnect(sd_bus *bus);
DESCRIPTION¶sd_bus_set_exit_on_disconnect() may be used to configure the exit behavior when the given bus object disconnects. If b is zero, no special logic is executed when the bus object disconnects. If b is non-zero, the behavior on disconnect depends on whether the bus object is attached to an event loop or not. If the bus object is attached to an event loop (see sd_bus_attach_event(3)), the event loop is closed when the bus object disconnects (as if calling sd_event_exit(3)). Otherwise, exit(3) is called. The exit code passed to sd_event_exit() and exit() is EXIT_FAILURE. If the bus object has already disconnected when enabling the exit behavior, the exit behavior is executed immediately. By default, the exit behavior is disabled.
sd_bus_get_exit_on_disconnect() returns whether the exit on disconnect behavior is enabled for the given bus object.
RETURN VALUE¶On success, sd_bus_set_exit_on_disconnect() returns a non-negative integer. On failure, it returns a negative errno-style error code.
sd_bus_get_exit_on_disconnect() returns a positive integer if the exit on disconnect behavior is enabled. Otherwise, it returns zero.
Errors¶Returned errors may indicate the following problems:
