/**
 * A `GSocket` is a low-level networking primitive. It is a more or less
 * direct mapping of the BSD socket API in a portable GObject based API.
 * It supports both the UNIX socket implementations and winsock2 on Windows.
 * 
 * `GSocket` is the platform independent base upon which the higher level
 * network primitives are based. Applications are not typically meant to
 * use it directly, but rather through classes like [class@Gio.SocketClient],
 * [class@Gio.SocketService] and [class@Gio.SocketConnection]. However there may
 * be cases where direct use of `GSocket` is useful.
 * 
 * `GSocket` implements the [iface@Gio.Initable] interface, so if it is manually
 * constructed by e.g. [ctor@GObject.Object.new] you must call
 * [method@Gio.Initable.init] and check the results before using the object.
 * This is done automatically in [ctor@Gio.Socket.new] and
 * [ctor@Gio.Socket.new_from_fd], so these functions can return `NULL`.
 * 
 * Sockets operate in two general modes, blocking or non-blocking. When
 * in blocking mode all operations (which don’t take an explicit blocking
 * parameter) block until the requested operation
 * is finished or there is an error. In non-blocking mode all calls that
 * would block return immediately with a `G_IO_ERROR_WOULD_BLOCK` error.
 * To know when a call would successfully run you can call
 * [method@Gio.Socket.condition_check], or [method@Gio.Socket.condition_wait].
 * You can also use [method@Gio.Socket.create_source] and attach it to a
 * [type@GLib.MainContext] to get callbacks when I/O is possible.
 * Note that all sockets are always set to non blocking mode in the system, and
 * blocking mode is emulated in `GSocket`.
 * 
 * When working in non-blocking mode applications should always be able to
 * handle getting a `G_IO_ERROR_WOULD_BLOCK` error even when some other
 * function said that I/O was possible. This can easily happen in case
 * of a race condition in the application, but it can also happen for other
 * reasons. For instance, on Windows a socket is always seen as writable
 * until a write returns `G_IO_ERROR_WOULD_BLOCK`.
 * 
 * `GSocket`s can be either connection oriented or datagram based.
 * For connection oriented types you must first establish a connection by
 * either connecting to an address or accepting a connection from another
 * address. For connectionless socket types the target/source address is
 * specified or received in each I/O operation.
 * 
 * All socket file descriptors are set to be close-on-exec.
 * 
 * Note that creating a `GSocket` causes the signal `SIGPIPE` to be
 * ignored for the remainder of the program. If you are writing a
 * command-line utility that uses `GSocket`, you may need to take into
 * account the fact that your program will not automatically be killed
 * if it tries to write to `stdout` after it has been closed.
 * 
 * Like most other APIs in GLib, `GSocket` is not inherently thread safe. To use
 * a `GSocket` concurrently from multiple threads, you must implement your own
 * locking.
 * 
 * ## Nagle’s algorithm
 * 
 * Since GLib 2.80, `GSocket` will automatically set the `TCP_NODELAY` option on
 * all `G_SOCKET_TYPE_STREAM` sockets. This disables
 * [Nagle’s algorithm](https://en.wikipedia.org/wiki/Nagle%27s_algorithm) as it
 * typically does more harm than good on modern networks.
 * 
 * If your application needs Nagle’s algorithm enabled, call
 * [method@Gio.Socket.set_option] after constructing a `GSocket` to enable it:
 * ```c
 * socket = g_socket_new (…, G_SOCKET_TYPE_STREAM, …);
 * if (socket != NULL)
 * {
 * g_socket_set_option (socket, IPPROTO_TCP, TCP_NODELAY, FALSE, &local_error);
 * // handle error if needed
 * }
 * ```
 *
 * Since: 2.22
