NAME

6       sd_bus_set_exit_on_disconnect, sd_bus_get_exit_on_disconnect - Control
7       the exit behavior when the bus object disconnects
8

SYNOPSIS

10       #include <systemd/sd-bus.h>
11
12       int sd_bus_set_exit_on_disconnect(sd_bus *bus, int b);
13
14       int sd_bus_get_exit_on_disconnect(sd_bus *bus);
15

DESCRIPTION

17       sd_bus_set_exit_on_disconnect() may be used to configure the exit
18       behavior when the given bus object disconnects. If b is zero, no
19       special logic is executed when the bus object disconnects. If b is
20       non-zero, the behavior on disconnect depends on whether the bus object
21       is attached to an event loop or not. If the bus object is attached to
22       an event loop (see sd_bus_attach_event(3)), the event loop is closed
23       when the bus object disconnects (as if calling sd_event_exit(3)).
24       Otherwise, exit(3) is called. The exit code passed to sd_event_exit()
25       and exit() is EXIT_FAILURE. If the bus object has already disconnected
26       when enabling the exit behavior, the exit behavior is executed
27       immediately. By default, the exit behavior is disabled.
28
29       sd_bus_get_exit_on_disconnect() returns whether the exit on disconnect
30       behavior is enabled for the given bus object.
31

RETURN VALUE

33       On success, sd_bus_set_exit_on_disconnect() returns a non-negative
34       integer. On failure, it returns a negative errno-style error code.
35
36       sd_bus_get_exit_on_disconnect() returns a positive integer if the exit
37       on disconnect behavior is enabled. Otherwise, it returns zero.
38
39   Errors
40       Returned errors may indicate the following problems:
41
42       -EINVAL
43           A required parameter was NULL.
44
45       -ENOPKG
46           The bus object could not be resolved.
47
48       -ECHILD
49           The bus connection was created in a different process.
