NAMEsd_bus_set_exit_on_disconnect, sd_bus_get_exit_on_disconnect − Control the exit behavior when the bus object disconnects
SYNOPSIS#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);
DESCRIPTIONsd_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 VALUEOn 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.
ErrorsReturned 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.
NOTESThese APIs are implemented as a shared library, which can be compiled and linked to with the libsystemd pkg-config(1) file.
