Description

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.

Functions

g_socket_client_new ()

GSocketClient *
g_socket_client_new (void);

Creates a new GSocketClient with the default options.

Returns

a GSocketClient. Free the returned object with g_object_unref().

g_socket_client_connect ()

GSocketConnection *
g_socket_client_connect (GSocketClient *client,
                         GSocketConnectable *connectable,
                         GCancellable *cancellable,
                         GError **error);

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

Upon a successful connection, a new GSocketConnection is constructed and returned. The caller owns this new object and must drop their reference to it when finished with it.

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

The socket created will be the same family as the address that the connectable resolves to, unless family is set with g_socket_client_set_family() or indirectly via g_socket_client_set_local_address(). The socket type defaults to G_SOCKET_TYPE_STREAM but can be set with g_socket_client_set_socket_type().

If a local address is specified with g_socket_client_set_local_address() the socket will be bound to this address before connecting.

Parameters

client

a GSocketClient.

 

connectable

a GSocketConnectable specifying the remote address.

 

cancellable

optional GCancellable object, NULL to ignore.

[allow-none]

error

GError for error reporting, or NULL to ignore.

 

Returns

a GSocketConnection on success, NULL on error.

g_socket_client_connect_to_host ()

GSocketConnection *
g_socket_client_connect_to_host (GSocketClient *client,
                                 const gchar *host_and_port,
                                 guint16 default_port,
                                 GCancellable *cancellable,
                                 GError **error);

This is a helper function for g_socket_client_connect().

Attempts to create a TCP connection to the named host.

host_and_port may be in any of a number of recognized formats; an IPv6 address, an IPv4 address, or a domain name (in which case a DNS lookup is performed). Quoting with [] is supported for all address types. A port override may be specified in the usual way with a colon. Ports may be given as decimal numbers or symbolic names (in which case an /etc/services lookup is performed).

If no port override is given in host_and_port then default_port will be used as the port number to connect to.

In general, host_and_port is expected to be provided by the user (allowing them to give the hostname, and a port override if necessary) and default_port is expected to be provided by the application.

In the case that an IP address is given, a single connection attempt is made. In the case that a name is given, multiple connection attempts may be made, in turn and according to the number of address records in DNS, until a connection succeeds.

Upon a successful connection, a new GSocketConnection is constructed and returned. The caller owns this new object and must drop their reference to it when finished with it.

In the event of any failure (DNS error, service not found, no hosts connectable) NULL is returned and error (if non-NULL) is set accordingly.

Parameters

client

a GSocketClient

 

host_and_port

the name and optionally port of the host to connect to

 

default_port

the default port to connect to

 

cancellable

a GCancellable, or NULL.

[allow-none]

error

a pointer to a GError, or NULL

 

Returns

a GSocketConnection on success, NULL on error.

                                    GError **error);

Attempts to create a TCP connection to a service.

This call looks up the SRV record for service at domain for the "tcp" protocol. It then attempts to connect, in turn, to each of the hosts providing the service until either a connection succeeds or there are no hosts remaining.

Upon a successful connection, a new GSocketConnection is constructed and returned. The caller owns this new object and must drop their reference to it when finished with it.

In the event of any failure (DNS error, service not found, no hosts connectable) NULL is returned and error (if non-NULL) is set accordingly.

g_socket_client_connect_to_uri ()

GSocketConnection *
g_socket_client_connect_to_uri (GSocketClient *client,
                                const gchar *uri,
                                guint16 default_port,

                                GError **error);

This is a helper function for g_socket_client_connect().

Attempts to create a TCP connection with a network URI.

uri may be any valid URI containing an "authority" (hostname/port) component. If a port is not specified in the URI, default_port will be used. TLS will be negotiated if “tls” is TRUE. (GSocketClient does not know to automatically assume TLS for certain URI schemes.)

Using this rather than g_socket_client_connect() or g_socket_client_connect_to_host() allows GSocketClient to determine when to use application-specific proxy protocols.

Upon a successful connection, a new GSocketConnection is constructed and returned. The caller owns this new object and must drop their reference to it when finished with it.

In the event of any failure (DNS error, service not found, no hosts connectable) NULL is returned and error (if non-NULL) is set accordingly.

Parameters

client

a GSocketClient

 

uri

A network URI

 

default_port

the default port to connect to

 

cancellable

a GCancellable, or NULL.

[allow-none]

error

a pointer to a GError, or NULL

 

Returns

void
g_socket_client_set_family (GSocketClient *client,
                            GSocketFamily 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.

This might be useful for instance if you want to force the local connection to be an ipv4 socket, even though the address might be an ipv6 mapped to ipv4 address.

Parameters

client

a GSocketClient.

 

family

a GSocketFamily

 

Since: 2.22


g_socket_client_set_local_address ()

void
g_socket_client_set_local_address (GSocketClient *client,
                                   GSocketAddress *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.

This is useful if you want to ensure that the local side of the connection is on a specific port, or on a specific interface.

Parameters

client

a GSocketClient.

 

address

a GSocketAddress, or NULL.

[allow-none]

Since: 2.22


g_socket_client_set_protocol ()

void
g_socket_client_set_protocol (GSocketClient *client,
                              GSocketProtocol protocol);

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

If protocol is 0 that means to use the default protocol for the socket family and type.

Parameters

client

a GSocketClient.

 

protocol

a GSocketProtocol

 

Since: 2.22


g_socket_client_set_socket_type ()

void
g_socket_client_set_socket_type (GSocketClient *client,
                                 GSocketType type);

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

It doesn't make sense to specify a type of G_SOCKET_TYPE_DATAGRAM, as GSocketClient is used for connection oriented services.

Parameters

client

a GSocketClient.

 

type

a GSocketType

 

Since: 2.22


g_socket_client_set_timeout ()

void
g_socket_client_set_timeout (GSocketClient *client,
                             guint timeout);

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

The timeout value affects the initial connection attempt as well, so setting this may cause calls to g_socket_client_connect(), etc, to fail with G_IO_ERROR_TIMED_OUT.

Parameters

client

a GSocketClient.

 

timeout

the timeout

 

Since: 2.26


g_socket_client_set_enable_proxy ()

void
g_socket_client_set_enable_proxy (GSocketClient *client,
                                  gboolean enable);

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.

See also g_socket_client_set_proxy_resolver().

Parameters

client

a GSocketClient.

 

enable

whether to enable proxies

 

Since: 2.26


g_socket_client_set_proxy_resolver ()

void
g_socket_client_set_proxy_resolver (GSocketClient *client,
                                    GProxyResolver *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.

Note that whether or not the proxy resolver is actually used depends on the setting of “enable-proxy”, which is not changed by this function (but which is TRUE by default)

Parameters

client

a GSocketClient.

 

proxy_resolver

a GProxyResolver, or NULL for the default.

[allow-none]

Since: 2.36


g_socket_client_set_tls ()

void
g_socket_client_set_tls (GSocketClient *client,
                         gboolean 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.

Note that since GSocketClient must return a GSocketConnection, but GTlsClientConnection is not a GSocketConnection, this actually wraps the resulting GTlsClientConnection in a GTcpWrapperConnection when returning it. You can use g_tcp_wrapper_connection_get_base_io_stream() on the return value to extract the GTlsClientConnection.

If you need to modify the behavior of the TLS handshake (eg, by setting a client-side certificate to use, or connecting to the “accept-certificate” signal), you can connect to client 's “event” signal and wait for it to be emitted with G_SOCKET_CLIENT_TLS_HANDSHAKING, which will give you a chance to see the GTlsClientConnection before the handshake starts.

Parameters

client

a GSocketClient.

 

tls

whether to use TLS

g_socket_client_add_application_proxy ()

void
g_socket_client_add_application_proxy (GSocketClient *client,
                                       const gchar *protocol);

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.

This should be used for proxy protocols that are dialects of another protocol such as HTTP proxy. It also allows cohabitation of proxy protocols that are reused between protocols. A good example is HTTP. It can be used to proxy HTTP, FTP and Gopher and can also be use as generic socket proxy through the HTTP CONNECT method.

When the proxy is detected as being an application proxy, TLS handshake will be skipped. This is required to let the application do the proxy specific handshake.

Parameters

client

a GSocketClient

 

protocol

The proxy protocol

 

Types and Values

Signal Details

The “event” signal

void
user_function (GSocketClient      *client,
               GSocketClientEvent  event,
               GSocketConnectable *connectable,
               GIOStream          *connection,
               gpointer            user_data)

Emitted when client 's activity on connectable changes state. Among other things, this can be used to provide progress information about a network connection in the UI. The meanings of the different event values are as follows:

Each event except G_SOCKET_CLIENT_COMPLETE may be emitted multiple times (or not at all) for a given connectable (in particular, if client ends up attempting to connect to more than one address). However, if client emits the “event” signal at all for a given connectable, that it will always emit it with G_SOCKET_CLIENT_COMPLETE when it is done.

Note that there may be additional GSocketClientEvent values in the future; unrecognized event values should be ignored.

Parameters

client

the GSocketClient

 

event

the event that is occurring

 

connectable

the GSocketConnectable that event is occurring on

 

connection

the current representation of the connection.

[nullable]

user_data

user data set when the signal handler was connected.
