## Description

`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.

## Return Value

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.
