NAME

6       sd_bus_set_close_on_exit, sd_bus_get_close_on_exit - Control whether to
7       close the bus connection during the event loop exit phase
8

SYNOPSIS

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

DESCRIPTION

17       sd_bus_set_close_on_exit() may be used to enable or disable whether the
18       bus connection is automatically flushed (as in sd_bus_flush(3)) and
19       closed (as in sd_bus_close(3)) during the exit phase of the event loop.
20       This logic only applies to bus connections that are attached to an sd-
21       event(3) event loop, see sd_bus_attach_event(3). By default this
22       mechanism is enabled and makes sure that any pending messages that have
23       not been written to the bus connection are written out when the event
24       loop is shutting down. In some cases this behaviour is not desirable,
25       for example when the bus connection shall remain usable until after the
26       event loop exited. If b is true, the feature is enabled (which is the
27       default), otherwise disabled.
28
29       sd_bus_get_close_on_exit() may be used to query the current setting of
30       this feature. It returns zero when the feature is disabled, and
31       positive if enabled.
32

RETURN VALUE

34       On success, sd_bus_set_close_on_exit() returns a non-negative integer.
35       On failure, it returns a negative errno-style error code.
36
37       sd_bus_get_close_on_exit() returns 0 if the feature is currently
38       disabled or a positive integer if it is enabled. On failure, it returns
39       a negative errno-style error code.
40
41   Errors
42       Returned errors may indicate the following problems:
43
44       -ECHILD
45           The bus connection was created in a different process.

NOTES

48       These APIs are implemented as a shared library, which can be compiled
49       and linked to with the libsystemd pkg-config(1) file.
