* @short_description: A threaded GSocketService
2014-01-07 22:55:43 -05:00
* @include: gio/gio.h
* @see_also: #GSocketService.
*
* A #GThreadedSocketService is a simple subclass of #GSocketService
* that handles incoming connections by creating a worker thread and
2011-06-04 18:44:44 -04:00
* dispatching the connection to it by emitting the
* #GThreadedSocketService::run signal in the new thread.
*
* The signal handler may perform blocking IO and need not return
* until the connection is closed.
*
* The service is implemented using a thread pool, so there is a
2011-04-20 19:08:06 +02:00
* limited amount of threads available to serve incoming requests.
* The service automatically stops the #GSocketService from accepting
* new connections when all threads are busy.
*
2011-06-04 18:44:44 -04:00
* As with #GSocketService, you may connect to #GThreadedSocketService::run,
* or subclass and override the default handler.
