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  *

1514 	 *
1515 	 * If @address is %NULL then the message is sent to the default receiver
1516 	 * (set by g_socket_connect()).
1517 	 *
1518 	 * @vectors must point to an array of #GOutputVector structs and
1519 	 * @num_vectors must be the length of this array. (If @num_vectors is -1,
1520 	 * then @vectors is assumed to be terminated by a #GOutputVector with a
1521 	 * %NULL buffer pointer.) The #GOutputVector structs describe the buffers
1522 	 * that the sent data will be gathered from. Using multiple
1523 	 * #GOutputVectors is more memory-efficient than manually copying
1524 	 * data from multiple sources into a single buffer, and more
1525 	 * network-efficient than making multiple calls to g_socket_send().
1526 	 *
1527 	 * @messages, if non-%NULL, is taken to point to an array of @num_messages
1528 	 * #GSocketControlMessage instances. These correspond to the control
1529 	 * messages to be sent on the socket.
1530 	 * If @num_messages is -1 then @messages is treated as a %NULL-terminated
1531 	 * array.
1532 	 *
1533 	 * @flags modify how the message is sent. The commonly available arguments
1534 	 * for this are available in the #GSocketMsgFlags enum, but the
1535 	 * values there are the same as the system values, and the flags
1536 	 * are passed in as-is, so you can pass in system-specific flags too.
1537 	 *
1538 	 * If the socket is in blocking mode the call will block until there is
1539 	 * space for the data in the socket queue. If there is no space available
1540 	 * and the socket is in non-blocking mode a %G_IO_ERROR_WOULD_BLOCK error
1541 	 * will be returned. To be notified when space is available, wait for the
1542 	 * %G_IO_OUT condition. Note though that you may still receive
1543 	 * %G_IO_ERROR_WOULD_BLOCK from g_socket_send() even if you were previously
1544 	 * notified of a %G_IO_OUT condition. (On Windows in particular, this is
1545 	 * very common due to the way the underlying APIs work.)
1546 	 *
1547 	 * The sum of the sizes of each #GOutputVector in vectors must not be
1548 	 * greater than %G_MAXSSIZE. If the message can be larger than this,
1549 	 * then it is mandatory to use the g_socket_send_message_with_timeout()
1550 	 * function.
1551 	 *
1552 	 * On error -1 is returned and @error is set accordingly.
1553 	 *
