48  * A #GSocket is a low-level networking primitive. It is a more or less
49  * direct mapping of the BSD socket API in a portable GObject based API.
50  * It supports both the UNIX socket implementations and winsock2 on Windows.
51  * 
52  * #GSocket is the platform independent base upon which the higher level
53  * network primitives are based. Applications are not typically meant to
54  * use it directly, but rather through classes like #GSocketClient,
55  * #GSocketService and #GSocketConnection. However there may be cases where
56  * direct use of #GSocket is useful.
57  * 
58  * #GSocket implements the #GInitable interface, so if it is manually constructed
59  * by e.g. g_object_new() you must call g_initable_init() and check the
60  * results before using the object. This is done automatically in
61  * g_socket_new() and g_socket_new_from_fd(), so these functions can return
62  * %NULL.
63  * 
64  * Sockets operate in two general modes, blocking or non-blocking. When
65  * in blocking mode all operations (which don’t take an explicit blocking
66  * parameter) block until the requested operation
67  * is finished or there is an error. In non-blocking mode all calls that
68  * would block return immediately with a %G_IO_ERROR_WOULD_BLOCK error.
69  * To know when a call would successfully run you can call g_socket_condition_check(),
70  * or g_socket_condition_wait(). You can also use g_socket_create_source() and
71  * attach it to a #GMainContext to get callbacks when I/O is possible.
72  * Note that all sockets are always set to non blocking mode in the system, and
73  * blocking mode is emulated in GSocket.
74  * 
75  * When working in non-blocking mode applications should always be able to
76  * handle getting a %G_IO_ERROR_WOULD_BLOCK error even when some other
77  * function said that I/O was possible. This can easily happen in case
78  * of a race condition in the application, but it can also happen for other
79  * reasons. For instance, on Windows a socket is always seen as writable
80  * until a write returns %G_IO_ERROR_WOULD_BLOCK.
81  * 
82  * #GSockets can be either connection oriented or datagram based.
83  * For connection oriented types you must first establish a connection by
84  * either connecting to an address or accepting a connection from another
85  * address. For connectionless socket types the target/source address is
86  * specified or received in each I/O operation.
87  * 
88  * All socket file descriptors are set to be close-on-exec.
89  * 
90  * Note that creating a #GSocket causes the signal %SIGPIPE to be
91  * ignored for the remainder of the program. If you are writing a
92  * command-line utility that uses #GSocket, you may need to take into
93  * account the fact that your program will not automatically be killed
94  * if it tries to write to %stdout after it has been closed.
95  * 
96  * Like most other APIs in GLib, #GSocket is not inherently thread safe. To use
97  * a #GSocket concurrently from multiple threads, you must implement your own
98  * locking.
99  *

1509 	 * Send multiple data messages from @socket in one go.  This is the most
1510 	 * complicated and fully-featured version of this call. For easier use, see
1511 	 * g_socket_send(), g_socket_send_to(), and g_socket_send_message().
1512 	 *
1513 	 * @messages must point to an array of #GOutputMessage structs and
1514 	 * @num_messages must be the length of this array. Each #GOutputMessage
1515 	 * contains an address to send the data to, and a pointer to an array of
1516 	 * #GOutputVector structs to describe the buffers that the data to be sent
1517 	 * for each message will be gathered from. Using multiple #GOutputVectors is
1518 	 * more memory-efficient than manually copying data from multiple sources
1519 	 * into a single buffer, and more network-efficient than making multiple
1520 	 * calls to g_socket_send(). Sending multiple messages in one go avoids the
1521 	 * overhead of making a lot of syscalls in scenarios where a lot of data
1522 	 * packets need to be sent (e.g. high-bandwidth video streaming over RTP/UDP),
1523 	 * or where the same data needs to be sent to multiple recipients.
1524 	 *
1525 	 * @flags modify how the message is sent. The commonly available arguments
1526 	 * for this are available in the #GSocketMsgFlags enum, but the
1527 	 * values there are the same as the system values, and the flags
1528 	 * are passed in as-is, so you can pass in system-specific flags too.
1529 	 *
1530 	 * If the socket is in blocking mode the call will block until there is
1531 	 * space for all the data in the socket queue. If there is no space available
1532 	 * and the socket is in non-blocking mode a %G_IO_ERROR_WOULD_BLOCK error
1533 	 * will be returned if no data was written at all, otherwise the number of
1534 	 * messages sent will be returned. To be notified when space is available,
1535 	 * wait for the %G_IO_OUT condition. Note though that you may still receive
1536 	 * %G_IO_ERROR_WOULD_BLOCK from g_socket_send() even if you were previously
1537 	 * notified of a %G_IO_OUT condition. (On Windows in particular, this is
1538 	 * very common due to the way the underlying APIs work.)
1539 	 *
1540 	 * On error -1 is returned and @error is set accordingly. An error will only
1541 	 * be returned if zero messages could be sent; otherwise the number of messages
1542 	 * successfully sent before the error will be returned.
1543 	 *
1544 	 * Params:
1545 	 *     messages = an array of #GOutputMessage structs
