SD_BUS_SET_EXIT_ON_DISCONNECT(3)et_exit_on_disconnectT_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_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.
Errors
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.
These APIs are implemented as a shared library, which can be compiled
and linked to with the libsystemd pkg-config(1) file.
