## Detailed Description

A threaded GSocketService.

A ThreadedSocketService is a simple subclass of SocketService that handles incoming connections by creating a worker thread and dispatching the connection to it by emitting the 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 limited amount of threads availible to serve incomming requests. The service automatically stops the SocketService from accepting new connections when all threads are busy.

As with SocketService, you may connect to ThreadedSocketService::signal_run(), or subclass and override the default handler.

Since glibmm 2.24:

ThreadedSocketService& Gio::ThreadedSocketService::operator= | ( | ThreadedSocketService&& | src | ) |

noexcept

Glib::PropertyProxy_ReadOnly< int > Gio::ThreadedSocketService::property_max_threads | ( |  | ) | const

The max number of threads handling clients for this service.

Returns
  A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

Glib::SignalProxy2< bool,const Glib::RefPtr<SocketConnection>&,const Glib::RefPtr<Glib::Object>& > Gio::ThreadedSocketService::signal_run | ( |  | ) |

Slot Prototype:
  `bool on_my_run(const Glib::RefPtr<SocketConnection>& connection, const Glib::RefPtr<Glib::Object>& source_object)`

The signal_run() signal is emitted in a worker thread in response to an incoming connection. This thread is dedicated to handling connection and may perform blocking IO. The signal handler need not return until the connection is closed.

Parameters

  connection | A new SocketConnection object.
  source_object | The source_object passed to g_socket_listener_add_address().

Returns
  `true` to stop further signal handlers from being called.

## Friends And Related Function Documentation

Glib::RefPtr< Gio::ThreadedSocketService > wrap | ( | GThreadedSocketService * | object,
|  | bool | take_copy = `false`
| ) |  |

related

A Glib::wrap() method for this object.

Parameters

  object | The C instance.
  take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns
  A C++ instance that wraps this C instance.
