## Detailed Description

Helper for accepting network client connections.

See Also
  ThreadedSocketService, SocketService.

A SocketListener is an object that keeps track of a set of server sockets and helps you accept sockets from any of the socket, either sync or async.

If you want to implement a network server, also look at SocketService and ThreadedSocketService which are subclass of SocketListener that makes this even easier.

|  | const Glib::RefPtr< Glib::Object >& | source_object,
|  | Glib::RefPtr< SocketAddress >& | effective_address
| ) |  |

Creates a socket of type type and protocol protocol, binds it to address and adds it to the set of sockets we're accepting sockets from.

Note that adding an IPv6 address, depending on the platform, may or may not result in a listener that also accepts IPv4 connections. For more deterministic behavior, see g_socket_listener_add_inet_port().

source_object will be passed out in the various calls to accept to identify this particular source, which is useful if you're listening on multiple addresses and do different things depending on what address is connected to.

If successful and effective_address is non-`0` then it will be set to the address that the binding actually occurred at. This is helpful for determining the port number that was used for when requesting a binding to port 0 (ie: "any port"). This address, if requested, belongs to the caller and must be freed.

Since glibmm 2.22:

Parameters

  address | A SocketAddress.
  type | A SocketType.
  protocol | A SocketProtocol.
  source_object | Optional Object identifying this source.
  effective_address | Location to store the address that was bound to, or `0`.
