void webkit_web_context_initialize_notification_permissions ( WebKitWebContext* context, GList* allowed_origins, GList* disallowed_origins )
Sets initial desktop notification permissions for the
disallowed_origins must each be
WebKitSecurityOrigin objects representing origins that will,
respectively, either always or never have permission to show desktop
WebKitNotificationPermissionRequest will ever be
generated for any of the security origins represented in
disallowed_origins. This function is necessary
because some webpages proactively check whether they have permission
to display notifications without ever creating a permission request.
This function only affects web processes that have not already been
created. The best time to call it is when handling
WebKitWebContext::initialize-notification-permissions so as to
ensure that new web processes receive the most recent set of permissions.
