systemd sd_bus_set_exit_on_disconnect 3 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_event3), the event loop is closed when the bus object disconnects (as if calling sd_event_exit3). Otherwise, exit3 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. Returned errors may indicate the following problems: -EINVAL A required parameter was NULL. -ENOPKG The bus object could not be resolved. -ECHILD The bus connection was created in a different process, library or module instance. sd_bus_set_exit_on_disconnect() and sd_bus_get_exit_on_disconnect() were added in version 246. systemd1 sd-bus3 sd_bus_attach_event3 sd-event3 sd_event_exit3
