SD_BUS_...SCONNECT(3) sd_bus_set_exit_on_disconnect SD_BUS_...SCONNECT(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.
Added in version 246.
-ENOPKG
The bus object could not be resolved.
Added in version 246.
-ECHILD
The bus connection was created in a different process, library
or module instance.
Added in version 246.
Functions described here are available as a shared library, which
can be compiled against and linked to with the
libsystemd pkg-config(1) file.
All functions listed here are thread-agnostic and only a single
thread may operate on a given object at any given time. Different
threads may access the same object at different times. Multiple
independent objects may be used from different threads in
parallel.
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.
