# Gio SocketClient

since: 2.22

#### Description [src]

    class Gio.SocketClient : GObject.Object
    {
      GSocketClientPrivate* priv
    }

`GSocketClient` is a lightweight high-level utility class for connecting to a network host using a connection oriented socket type.

You create a `GSocketClient` object, set any options you want, and then call a sync or async connect operation, which returns a `GSocketConnection` subclass on success.

The type of the `GSocketConnection` object returned depends on the type of the underlying socket that is in use. For instance, for a TCP/IP connection it will be a `GTcpConnection`.

As `GSocketClient` is a lightweight object, you don’t need to cache it. You can just create a new one any time you need one.

###### g_socket_client_new

Creates a new `GSocketClient` with the default options.

#### Instance methods

###### g_socket_client_add_application_proxy

Enable proxy protocols to be handled by the application. When the indicated proxy protocol is returned by the `GProxyResolver`, `GSocketClient` will consider this protocol as supported but will not try to find a `GProxy` instance to handle handshaking. The application must check for this case by calling `g_socket_connection_get_remote_address()` on the returned `GSocketConnection`, and seeing if it’s a `GProxyAddress` of the appropriate type, to determine whether or not it needs to handle the proxy handshaking itself.

###### g_socket_client_connect

Tries to resolve the `connectable` and make a network connection to it.

Attempts to create a TCP connection to a service.

###### g_socket_client_connect_to_service_async

This is the asynchronous version of g_socket_client_connect_to_service().

since: 2.22

###### g_socket_client_connect_to_service_finish

Finishes an async connect operation. See g_socket_client_connect_to_service_async().

since: 2.22

###### g_socket_client_connect_to_uri

This is a helper function for g_socket_client_connect().

since: 2.26

###### g_socket_client_connect_to_uri_async

This is the asynchronous version of g_socket_client_connect_to_uri().

since: 2.26

###### g_socket_client_connect_to_uri_finish

Finishes an async connect operation. See g_socket_client_connect_to_uri_async().

since: 2.26

###### g_socket_client_get_enable_proxy

Gets the proxy enable state; see g_socket_client_set_enable_proxy().

since: 2.26

###### g_socket_client_get_family

Gets the socket family of the socket client.

since: 2.22

###### g_socket_client_get_local_address

Gets the local address of the socket client.

since: 2.22

###### g_socket_client_get_protocol

Gets the protocol name type of the socket client.

since: 2.22

###### g_socket_client_get_proxy_resolver

Gets the `GProxyResolver` being used by `client`. Normally, this will be the resolver returned by g_proxy_resolver_get_default(), but you can override it with g_socket_client_set_proxy_resolver().

since: 2.36

###### g_socket_client_get_socket_type

Gets the socket type of the socket client.

###### g_socket_client_get_timeout

Gets the I/O timeout time for sockets created by `client`.

since: 2.26

###### g_socket_client_get_tls

Gets whether `client` creates TLS connections. See `g_socket_client_set_tls()` for details.

since: 2.28

###### g_socket_client_get_tls_validation_flags

Gets the TLS validation flags used creating TLS connections via `client`.

deprecated: 2.72 since: 2.28

###### g_socket_client_set_enable_proxy

Sets whether or not `client` attempts to make connections via a proxy server. When enabled (the default), `GSocketClient` will use a `GProxyResolver` to determine if a proxy protocol such as SOCKS is needed, and automatically do the necessary proxy negotiation.

since: 2.26

###### g_socket_client_set_family

Sets the socket family of the socket client. If this is set to something other than `G_SOCKET_FAMILY_INVALID` then the sockets created by this object will be of the specified family.

since: 2.22

###### g_socket_client_set_local_address

Sets the local address of the socket client. The sockets created by this object will bound to the specified address (if not `NULL`) before connecting.

since: 2.22

###### g_socket_client_set_protocol

Sets the protocol of the socket client. The sockets created by this object will use of the specified protocol.

since: 2.22

###### g_socket_client_set_proxy_resolver

Overrides the `GProxyResolver` used by `client`. You can call this if you want to use specific proxies, rather than using the system default proxy settings.

since: 2.36

###### g_socket_client_set_socket_type

Sets the socket type of the socket client. The sockets created by this object will be of the specified type.

since: 2.22

###### g_socket_client_set_timeout

Sets the I/O timeout for sockets created by `client`. `timeout` is a time in seconds, or 0 for no timeout (the default).

since: 2.26

###### g_socket_client_set_tls

Sets whether `client` creates TLS (aka SSL) connections. If `tls` is `TRUE`, `client` will wrap its connections in a `GTlsClientConnection` and perform a TLS handshake when connecting.

since: 2.28

###### g_socket_client_set_tls_validation_flags

Sets the TLS validation flags used when creating TLS connections via `client`. The default value is `G_TLS_CERTIFICATE_VALIDATE_ALL`.

deprecated: 2.72 since: 2.28
