Description
|
|
Packit Service |
ea0369 |
The libvirt API has the ability to provide applications with asynchronous
|
|
Packit Service |
ea0369 |
notifications of interesting events. To enable this functionality though,
|
|
Packit Service |
ea0369 |
applications must provide libvirt with an event loop implementation. The
|
|
Packit Service |
ea0369 |
libvirt-glib API provides such an implementation, which naturally integrates
|
|
Packit Service |
ea0369 |
with the GMain event loop framework.
|
|
Packit Service |
ea0369 |
To enable use of the GMain event loop glue, the gvir_event_register()
|
|
Packit Service |
ea0369 |
should be invoked. Once this is done, it is mandatory to have the default
|
|
Packit Service |
ea0369 |
GMain event loop run by a thread in the application, usually the primary
|
|
Packit Service |
ea0369 |
thread, eg by using gtk_main()g_application_run()
|

gvir_event_register (void);
|

Packit Service |

Registers a libvirt event loop implementation that is backed
|
|
Packit Service |
ea0369 |
by the default GMain context. If invoked more
|
|
Packit Service |
ea0369 |
than once this method will be a no-op. Applications should,
|
|
Packit Service |
ea0369 |
however, take care not to register any another non-GLib
|
|
Packit Service |
ea0369 |
event loop with libvirt.
|
|
Packit Service |
ea0369 |
After invoking this method, it is mandatory to run the
|
|
Packit Service |
ea0369 |
default GMain event loop. Typically this can be satisfied
|
|
Packit Service |
ea0369 |
by invoking gtk_main or g_application_run
|
|
Packit Service |
ea0369 |
in the application's main thread. Failure to run the event
|
|
Packit Service |
ea0369 |
loop will mean no libvirt events get dispatched, and the
|
|
Packit Service |
ea0369 |
libvirt keepalive timer will kill off libvirt connections
|
|
Packit Service |
ea0369 |
frequently.
