SocketClient

#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

addApplicationProxy void addApplicationProxy(string 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.
addOnEvent gulong addOnEvent(void delegate(GSocketClientEvent, SocketConnectableIF, IOStream, SocketClient) dlg, ConnectFlags connectFlags): 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:
connect SocketConnection connect(SocketConnectableIF connectable, Cancellable cancellable): Tries to resolve the @connectable and make a network connection to it.
connectAsync void connectAsync(SocketConnectableIF connectable, Cancellable cancellable, GAsyncReadyCallback callback, void* userData): This is the asynchronous version of g_socket_client_connect().
connectFinish SocketConnection connectFinish(AsyncResultIF result): Finishes an async connect operation. See g_socket_client_connect_async()
connectToHost SocketConnection connectToHost(string hostAndPort, ushort defaultPort, Cancellable cancellable): This is a helper function for g_socket_client_connect().
connectToHostAsync void connectToHostAsync(string hostAndPort, ushort defaultPort, Cancellable cancellable, GAsyncReadyCallback callback, void* userData): This is the asynchronous version of g_socket_client_connect_to_host().
connectToHostFinish SocketConnection connectToHostFinish(AsyncResultIF result): Finishes an async connect operation. See g_socket_client_connect_to_host_async()
connectToService SocketConnection connectToService(string domain, string service, Cancellable cancellable): Attempts to create a TCP connection to a service.
connectToServiceAsync void connectToServiceAsync(string domain, string service, Cancellable cancellable, GAsyncReadyCallback callback, void* userData): This is the asynchronous version of g_socket_client_connect_to_service().
connectToServiceFinish SocketConnection connectToServiceFinish(AsyncResultIF result): Finishes an async connect operation. See g_socket_client_connect_to_service_async()
connectToUri SocketConnection connectToUri(string uri, ushort defaultPort, Cancellable cancellable): This is a helper function for g_socket_client_connect().
connectToUriAsync void connectToUriAsync(string uri, ushort defaultPort, Cancellable cancellable, GAsyncReadyCallback callback, void* userData): This is the asynchronous version of g_socket_client_connect_to_uri().
connectToUriFinish SocketConnection connectToUriFinish(AsyncResultIF result): Finishes an async connect operation. See g_socket_client_connect_to_uri_async()

getFamily GSocketFamily getFamily(): Gets the socket family of the socket client.
getLocalAddress SocketAddress getLocalAddress(): Gets the local address of the socket client.
getProtocol GSocketProtocol getProtocol(): Gets the protocol name type of the socket client.
getProxyResolver ProxyResolverIF getProxyResolver(): 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().
getSocketClientStruct GSocketClient* getSocketClientStruct(bool transferOwnership): Get the main Gtk struct
getSocketType GSocketType getSocketType(): Gets the socket type of the socket client.
getStruct void* getStruct(): the main Gtk struct as a void*
getTimeout uint getTimeout(): Gets the I/O timeout time for sockets created by @client.
getTls bool getTls(): Gets whether @client creates TLS connections. See g_socket_client_set_tls() for details.
getTlsValidationFlags GTlsCertificateFlags getTlsValidationFlags(): Gets the TLS validation flags used creating TLS connections via @client.
setEnableProxy void setEnableProxy(bool 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.
setFamily void setFamily(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.
setLocalAddress void setLocalAddress(SocketAddress 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.
setProtocol void setProtocol(GSocketProtocol protocol): Sets the protocol of the socket client. The sockets created by this object will use of the specified protocol.
setProxyResolver void setProxyResolver(ProxyResolverIF proxyResolver): 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.
setSocketType void setSocketType(GSocketType type): Sets the socket type of the socket client. The sockets created by this object will be of the specified type.
setTimeout void setTimeout(uint timeout): Sets the I/O timeout for sockets created by @client. @timeout is a time in seconds, or 0 for no timeout (the default).
setTls void setTls(bool 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.
setTlsValidationFlags void setTlsValidationFlags(GTlsCertificateFlags flags): Sets the TLS validation flags used when creating TLS connections via @client. The default value is %G_TLS_CERTIFICATE_VALIDATE_ALL.

doref deprecated ObjectG doref(ObjectG obj): Undocumented in source. Be warned that the author may not have intended to support it.
addOnNotify gulong addOnNotify(void delegate(ParamSpec, ObjectG) dlg, string property, ConnectFlags connectFlags): The notify signal is emitted on an object when one of its properties has been changed. Note that getting this signal doesn't guarantee that the value of the property has actually changed, it may also be emitted when the setter for the property is called to reinstate the previous value.
getType GType getType()
compatControl size_t compatControl(size_t what, void* data)
interfaceFindProperty ParamSpec interfaceFindProperty(TypeInterface gIface, string propertyName): Find the #GParamSpec with the given name for an interface. Generally, the interface vtable passed in as @g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek().
interfaceInstallProperty void interfaceInstallProperty(TypeInterface gIface, ParamSpec pspec): Add a property to an interface; this is only useful for interfaces that are added to GObject-derived types. Adding a property to an interface forces all objects classes with that interface to have a compatible property. The compatible property could be a newly created #GParamSpec, but normally g_object_class_override_property() will be used so that the object class only needs to provide an implementation and inherits the property description, default value, bounds, and so forth from the interface property.
interfaceListProperties ParamSpec[] interfaceListProperties(TypeInterface gIface): Lists the properties of an interface.Generally, the interface vtable passed in as @g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek().
addToggleRef void addToggleRef(GToggleNotify notify, void* data): Increases the reference count of the object by one and sets a callback to be called when all other references to the object are dropped, or when this is already the last reference to the object and another reference is established.
addWeakPointer void addWeakPointer(void* weakPointerLocation): Adds a weak reference from weak_pointer to @object to indicate that the pointer located at @weak_pointer_location is only valid during the lifetime of @object. When the @object is finalized, @weak_pointer will be set to %NULL.
bindProperty Binding bindProperty(string sourceProperty, ObjectG target, string targetProperty, GBindingFlags flags): Creates a binding between @source_property on @source and @target_property on @target. Whenever the @source_property is changed the @target_property is updated using the same value. For instance:
bindPropertyFull Binding bindPropertyFull(string sourceProperty, ObjectG target, string targetProperty, GBindingFlags flags, GBindingTransformFunc transformTo, GBindingTransformFunc transformFrom, void* userData, GDestroyNotify notify): Complete version of g_object_bind_property().
bindPropertyWithClosures Binding bindPropertyWithClosures(string sourceProperty, ObjectG target, string targetProperty, GBindingFlags flags, Closure transformTo, Closure transformFrom): Creates a binding between @source_property on @source and @target_property on @target, allowing you to set the transformation functions to be used by the binding.
dupData void* dupData(string key, GDuplicateFunc dupFunc, void* userData): This is a variant of g_object_get_data() which returns a 'duplicate' of the value. @dup_func defines the meaning of 'duplicate' in this context, it could e.g. take a reference on a ref-counted object.
dupQdata void* dupQdata(GQuark quark, GDuplicateFunc dupFunc, void* userData): This is a variant of g_object_get_qdata() which returns a 'duplicate' of the value. @dup_func defines the meaning of 'duplicate' in this context, it could e.g. take a reference on a ref-counted object.
forceFloating void forceFloating(): This function is intended for #GObject implementations to re-enforce a floating[floating-ref] object reference. Doing this is seldom required: all #GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling g_object_ref_sink().
freezeNotify void freezeNotify(): Increases the freeze count on @object. If the freeze count is non-zero, the emission of "notify" signals on @object is stopped. The signals are queued until the freeze count is decreased to zero. Duplicate notifications are squashed so that at most one #GObject::notify signal is emitted for each property modified while the object is frozen.
getData void* getData(string key): Gets a named field from the objects table of associations (see g_object_set_data()).
getProperty void getProperty(string propertyName, Value value): Gets a property of an object. @value must have been initialized to the expected type of the property (or a type to which the expected type can be transformed) using g_value_init().
getQdata void* getQdata(GQuark quark): This function gets back user data pointers stored via g_object_set_qdata().
getValist void getValist(string firstPropertyName, void* varArgs): Gets properties of an object.
getv void getv(string[] names, Value[] values): Gets @n_properties properties for an @object. Obtained properties will be set to @values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.
isFloating bool isFloating(): Checks whether @object has a floating[floating-ref] reference.
notify void notify(string propertyName): Emits a "notify" signal for the property @property_name on @object.
notifyByPspec void notifyByPspec(ParamSpec pspec): Emits a "notify" signal for the property specified by @pspec on @object.
doref ObjectG doref(): Increases the reference count of @object.
refSink ObjectG refSink(): Increase the reference count of @object, and possibly remove the floating[floating-ref] reference, if @object has a floating reference.
removeToggleRef void removeToggleRef(GToggleNotify notify, void* data): Removes a reference added with g_object_add_toggle_ref(). The reference count of the object is decreased by one.
removeWeakPointer void removeWeakPointer(void* weakPointerLocation): Removes a weak reference from @object that was previously added using g_object_add_weak_pointer(). The @weak_pointer_location has to match the one used with g_object_add_weak_pointer().
replaceData bool replaceData(string key, void* oldval, void* newval, GDestroyNotify destroy, GDestroyNotify oldDestroy): Compares the user data for the key @key on @object with @oldval, and if they are the same, replaces @oldval with @newval.
replaceQdata bool replaceQdata(GQuark quark, void* oldval, void* newval, GDestroyNotify destroy, GDestroyNotify oldDestroy): Compares the user data for the key @quark on @object with @oldval, and if they are the same, replaces @oldval with @newval.
runDispose void runDispose(): Releases all references to other objects. This can be used to break reference cycles.
setData void setData(string key, void* data): Each object carries around a table of associations from strings to pointers. This function lets you set an association.
setDataFull void setDataFull(string key, void* data, GDestroyNotify destroy): Like g_object_set_data() except it adds notification for when the association is destroyed, either by setting it to a different value or when the object is destroyed.
setProperty void setProperty(string propertyName, Value value): Sets a property on an object.
setQdata void setQdata(GQuark quark, void* data): This sets an opaque, named pointer on an object. The name is specified through a #GQuark (retrived e.g. via g_quark_from_static_string()), and the pointer can be gotten back from the @object with g_object_get_qdata() until the @object is finalized. Setting a previously set user data pointer, overrides (frees) the old pointer set, using #NULL as pointer essentially removes the data stored.
setQdataFull void setQdataFull(GQuark quark, void* data, GDestroyNotify destroy): This function works like g_object_set_qdata(), but in addition, a void (*destroy) (gpointer) function may be specified which is called with @data as argument when the @object is finalized, or the data is being overwritten by a call to g_object_set_qdata() with the same @quark.
setValist void setValist(string firstPropertyName, void* varArgs): Sets properties on an object.
setv void setv(string[] names, Value[] values): Sets @n_properties properties for an @object. Properties to be set will be taken from @values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.
stealData void* stealData(string key): Remove a specified datum from the object's data associations, without invoking the association's destroy handler.
stealQdata void* stealQdata(GQuark quark): This function gets back user data pointers stored via g_object_set_qdata() and removes the @data from object without invoking its destroy() function (if any was set). Usually, calling this function is only required to update user data pointers with a destroy notifier, for example: |[ void object_add_to_user_list (GObject *object, const gchar *new_string) { // the quark, naming the object data GQuark quark_string_list = g_quark_from_static_string ("my-string-list"); // retrive the old string list GList *list = g_object_steal_qdata (object, quark_string_list);
thawNotify void thawNotify(): Reverts the effect of a previous call to g_object_freeze_notify(). The freeze count is decreased on @object and when it reaches zero, queued "notify" signals are emitted.
unref void unref(): Decreases the reference count of @object. When its reference count drops to 0, the object is finalized (i.e. its memory is freed).
watchClosure void watchClosure(Closure closure): This function essentially limits the life time of the @closure to the life time of the object. That is, when the object is finalized, the @closure is invalidated by calling g_closure_invalidate() on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, g_object_ref() and g_object_unref() are added as marshal guards to the @closure, to ensure that an extra reference count is held on @object during invocation of the @closure. Usually, this function will be called on closures that use this @object as closure data.
weakRef void weakRef(GWeakNotify notify, void* data): Adds a weak reference callback to an object. Weak references are used for notification when an object is finalized. They are called "weak references" because they allow you to safely hold a pointer to an object without calling g_object_ref() (g_object_ref() adds a strong reference, that is, forces the object to stay alive).
weakUnref void weakUnref(GWeakNotify notify, void* data): Removes a weak reference callback to an object.
clearObject void clearObject(ObjectG objectPtr): Clears a reference to a #GObject.
