NAME         top

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

SYNOPSIS         top

       #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);

DESCRIPTION         top

       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         top

       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.

NOTES         top

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