Description
class Gio.SocketService : Gio.SocketListener {
parent_instance: GSocketListener,
priv: GSocketServicePrivate*
}A GSocketService is an object that represents a service that
is provided to the network or over local sockets. When a new
connection is made to the service the GSocketService::incoming
signal is emitted.
A GSocketService is a subclass of GSocketListener and you need
to add the addresses you want to accept connections on with the
GSocketListener APIs.
There are two options for implementing a network service based on
GSocketService. The first is to create the service using
g_socket_service_new() and to connect to the
GSocketService::incoming signal. The second is to subclass
GSocketService and override the default signal handler implementation.
In either case, the handler must immediately return, or else it
will block additional incoming connections from being serviced.
If you are interested in writing connection handlers that contain
blocking code then see GThreadedSocketService.
The socket service runs on the main loop of the
thread-default context (see
g_main_context_push_thread_default()) of the thread it is
created in, and is not threadsafe in general. However, the calls to start and
stop the service are thread-safe so these can be used from threads that
handle incoming clients.

Constructors
g_socket_service_new
Creates a new GSocketService with no sockets to listen for.
New listeners can be added with e.g. g_socket_listener_add_address()
or g_socket_listener_add_inet_port().
since: 2.22
Instance methods
g_socket_service_is_active
Check whether the service is active or not. An active service will accept new clients that connect, while a non-active service will let connecting clients queue up until the service is started.
since: 2.22
g_socket_service_start
Restarts the service, i.e. start accepting connections from the added sockets when the mainloop runs. This only needs to be called after the service has been stopped from g_socket_service_stop().
since: 2.22
g_socket_service_stop
Stops the service, i.e. stops accepting connections from the added sockets when the mainloop runs.
since: 2.22
Methods inherited from GSocketListener (12)
g_socket_listener_accept
Blocks waiting for a client to connect to any of the sockets added
to the listener. Returns a GSocketConnection for the socket that was accepted.
since: 2.22
g_socket_listener_accept_async
This is the asynchronous version of g_socket_listener_accept().
since: 2.22
g_socket_listener_accept_finish
Finishes an async accept operation. See g_socket_listener_accept_async()
since: 2.22
g_socket_listener_accept_socket
Blocks waiting for a client to connect to any of the sockets added
to the listener. Returns the GSocket that was accepted.
since: 2.22
g_socket_listener_accept_socket_async
This is the asynchronous version of g_socket_listener_accept_socket().
since: 2.22
g_socket_listener_accept_socket_finish
Finishes an async accept operation. See g_socket_listener_accept_socket_async()
since: 2.22
g_socket_listener_add_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.
since: 2.22
g_socket_listener_add_any_inet_port
Listens for TCP connections on any available port number for both IPv6 and IPv4 (if each is available).
since: 2.24
g_socket_listener_add_inet_port
Helper function for g_socket_listener_add_address() that
creates a TCP/IP socket listening on IPv4 and IPv6 (if
supported) on the specified port on all interfaces.
since: 2.22
g_socket_listener_add_socket
Adds socket to the set of sockets that we try to accept
new clients from. The socket must be bound to a local
address and listened to.
since: 2.22
g_socket_listener_close
Closes all the sockets in the listener.
since: 2.22
g_socket_listener_set_backlog
Sets the listen backlog on the sockets in the listener. This must be called
before adding any sockets, addresses or ports to the GSocketListener (for
example, by calling g_socket_listener_add_inet_port()) to be effective.
since: 2.22
Properties
Properties inherited from GSocketListener (1)
Gio.SocketListener:listen-backlog
The number of outstanding connections in the listen queue.
since: 2.22
Signals
Gio.SocketService::incoming
The ::incoming signal is emitted when a new incoming connection
to service needs to be handled. The handler must initiate the
handling of connection, but may not block; in essence,
asynchronous operations must be used.
since: 2.22
Signals inherited from GSocketListener (1)
GSocketListener::event
Emitted when listener‘s activity on socket changes state.
Note that when listener is used to listen on both IPv4 and
IPv6, a separate set of signals will be emitted for each, and
the order they happen in is undefined.
since: 2.46
Signals inherited from GObject (1)
GObject::notify
The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
