/** Low-level socket object
 *
 * A Socket 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.
 *
 * Socket 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 SocketClient, SocketService and
 * SocketConnection. However there may be cases where direct use of Socket is
 * useful.
 *
 * Socket implements the Initable interface, and since initialization can fail,
 * the constructor may throw an exception.
 *
 * Sockets operate in two general modes, blocking or non-blocking. When in
 * blocking mode all operations 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 Gio::Error::WOULD_BLOCK error. To know when a call would
 * successfully run you can call condition_check(), or condition_wait(). You can
 * also use create_source() and attach it to a 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 Socket.
 *
 * When working in non-blocking mode applications should always be able to
 * handle getting a Gio::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 Gio::Error::WOULD_BLOCK.
 *
 * Sockets 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 Socket causes the signal SIGPIPE to be ignored for the
 * remainder of the program. If you are writing a command-line utility that uses
 * Socket, 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.
