sd_bus_set_exit_on_disconnect - Man Page

#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.

Functions described here are available as a shared library, which can be compiled against and linked to with the libsystemd pkg-config(1) file.

The code described here uses getenv(3), which is declared to be not multi-thread-safe. This means that the code calling the functions described here must not call setenv(3) from a parallel thread. It is recommended to only do calls to setenv() from an early phase of the program when no other threads have been started.

sd_bus_set_exit_on_disconnect() and sd_bus_get_exit_on_disconnect() were added in version 246.
