ResolverNameLookupFlags	Flags to modify lookup behavior.
Resource	Applications and libraries often contain binary or textual data that is really part of the application, rather than user data. For instance GtkBuilder .ui files, splashscreen images, GMenu markup XML, CSS files, icons, etc. These are often shipped as files in $datadir/appname, or manually included as literal strings in the code.
ResourceLookupFlags	GResourceLookupFlags determine how resource path lookups are handled.
Seekable	Seekable is implemented by streams (implementations of InputStream or OutputStream) that support seeking.
Settings	The Settings class provides a convenient API for storing and retrieving application settings.
SettingsBackend	The SettingsBackend interface defines a generic interface for non-strictly-typed data that is stored in a hierarchy. To implement an alternative storage backend for Settings, you need to implement the SettingsBackend interface and then make it implement the extension point SETTINGS_BACKEND_EXTENSION_POINT_NAME.
SettingsBindFlags	Flags used when creating a binding. These flags determine in which direction the binding works. The default is to synchronize in both directions.
SettingsSchema	The SettingsSchemaSource and SettingsSchema APIs provide a mechanism for advanced control over the loading of schemas and a mechanism for introspecting their content.

SocketConnection	SocketConnection is a IOStream for a connected socket. They can be created either by SocketClient when connecting to a host, or by SocketListener when accepting a new client.
SocketListener	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.
SocketService	A SocketService 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 signal::SocketService::incoming signal is emitted.
SrvTarget	SRV (service) records are used by some network protocols to provide service-specific aliasing and load-balancing. For example, XMPP (Jabber) uses SRV records to locate the XMPP server for a domain; rather than connecting directly to “example.com” or assuming a specific server hostname like “xmpp.example.com”, an XMPP client would look up the “xmpp-client” SRV record for “example.com”, and then connect to whatever host was pointed to by that record.
Subprocess	Subprocess allows the creation of and interaction with child processes.
SubprocessFlags	Flags to define the behaviour of a Subprocess.
SubprocessLauncher	This class contains a set of options for launching child processes, such as where its standard input and output will be directed, the argument list, the environment, and more.
Task	A Task represents and manages a cancellable “task”.
TcpConnection	This is the subclass of SocketConnection that is created for TCP/IP sockets.
ThemedIcon	ThemedIcon is an implementation of Icon that supports icon themes. ThemedIcon contains a list of all of the icons present in an icon theme, so that icons can be looked up quickly. ThemedIcon does not provide actual pixmaps for icons, just the icon names. Ideally something like gtk_icon_theme_choose_icon() should be used to resolve the list of names so that fallback icons work nicely with themes that inherit other themes.
ThreadedSocketService	A ThreadedSocketService is a simple subclass of SocketService that handles incoming connections by creating a worker thread and dispatching the connection to it by emitting the signal::ThreadedSocketService::run signal in the new thread.
TlsBackend	TLS (Transport Layer Security, aka SSL) and DTLS backend.
TlsCertificate	A certificate used for TLS authentication and encryption. This can represent either a certificate only (eg, the certificate received by a client from a server), or the combination of a certificate and a private key (which is needed when acting as a TlsServerConnection).
TlsCertificateFlags	A set of flags describing TLS certification validation. This can be used to set which validation steps to perform (eg, with TlsClientConnectionExt::set_validation_flags()), or to describe why a particular certificate was rejected (eg, in signal::TlsConnection::accept-certificate).
TlsClientConnection	TlsClientConnection is the client-side subclass of TlsConnection, representing a client-side TLS connection.
TlsConnection	TlsConnection is the base TLS connection class type, which wraps a IOStream and provides TLS encryption on top of it. Its subclasses, TlsClientConnection and TlsServerConnection, implement client-side and server-side TLS, respectively.
TlsDatabase	TlsDatabase is used to look up certificates and other information from a certificate or key store. It is an abstract base class which TLS library specific subtypes override.
TlsDatabaseVerifyFlags	Flags for TlsDatabaseExt::verify_chain().
TlsFileDatabase	TlsFileDatabase is implemented by TlsDatabase objects which load their certificate information from a file. It is an interface which TLS library specific subtypes implement.

UnixFDList	A UnixFDList contains a list of file descriptors. It owns the file descriptors that it contains, closing them when finalized.
UnixInputStream	UnixInputStream implements InputStream for reading from a UNIX file descriptor, including asynchronous operations. (If the file descriptor refers to a socket or pipe, this will use poll() to do asynchronous I/O. If it refers to a regular file, it will fall back to doing asynchronous I/O in another thread.)
UnixMountEntry	Defines a Unix mount entry (e.g. <filename>/media/cdrom</filename>). This corresponds roughly to a mtab entry.
UnixMountPoint	Defines a Unix mount point (e.g. <filename>/dev</filename>). This corresponds roughly to a fstab entry.
UnixOutputStream	UnixOutputStream implements OutputStream for writing to a UNIX file descriptor, including asynchronous operations. (If the file descriptor refers to a socket or pipe, this will use poll() to do asynchronous I/O. If it refers to a regular file, it will fall back to doing asynchronous I/O in another thread.)
UnixSocketAddress	Support for UNIX-domain (also known as local) sockets.
Vfs	Entry point for using GIO functionality.
Volume	The Volume interface represents user-visible objects that can be mounted. Note, when porting from GnomeVFS, Volume is the moral equivalent of GnomeVFSDrive.
