sd_bus_set_exit_on_disconnect, sd_bus_get_exit_on_disconnect - Control the exit behavior when the bus object disconnects

  #include <systemd/sd-bus.h>

int sd_bus_set_exit_on_disconnect(sd_bus **/bus/, int b);*

int sd_bus_get_exit_on_disconnect(sd_bus **/bus/);*

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.

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.

These APIs are implemented as a shared library, which can be compiled and linked to with the libsystemd *pkg-config*(1) file.
