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.

add_address() [1/2]

		Socket::Type	type,
		Socket::Protocol	protocol,
		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-nullptr 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.

Call g_socket_listener_close() to stop listening on address; this will not be done automatically when you drop your final reference to listener, as references may be held internally.

Since glibmm 2.22:

Parameters

address	A SocketAddress.
type	A Gio::Socket::Type.
protocol	A Gio::Socket::Protocol.
source_object	Optional Object identifying this source.
effective_address	Location to store the address that was bound to, or nullptr.

Returns

true on success, false on error.

static GType Gio::SocketListener::get_type ( )

static

Get the GType for this class, for use with the underlying GObject type system.

gobj() [1/2]

GSocketListener * Gio::SocketListener::gobj ( )

inline

Provides access to the underlying C GObject.

gobj() [2/2]

const GSocketListener * Gio::SocketListener::gobj ( ) const

inline

Provides access to the underlying C GObject.

gobj_copy()

GSocketListener * Gio::SocketListener::gobj_copy

(

)

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

operator=()

SocketListener & Gio::SocketListener::operator= ( SocketListener &&  src )

noexcept

property_listen_backlog() [1/2]

Glib::PropertyProxy< int > Gio::SocketListener::property_listen_backlog

(

)

The number of outstanding connections in the listen queue.

Since glibmm 2.22:

Default value: 10

Returns

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

property_listen_backlog() [2/2]

Glib::PropertyProxy_ReadOnly< int > Gio::SocketListener::property_listen_backlog

(

)

const

The number of outstanding connections in the listen queue.

Since glibmm 2.22:

Default value: 10

Returns

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

set_backlog()

void Gio::SocketListener::set_backlog

(

int

listen_backlog

)

Sets the listen backlog on the sockets in the listener.

This must be called before adding any sockets, addresses or ports to the SocketListener (for example, by calling g_socket_listener_add_inet_port()) to be effective.

See g_socket_set_listen_backlog() for details

Since glibmm 2.22:

Parameters

listen_backlog

An integer.
