49  * A #GSocket is a low-level networking primitive. It is a more or less
50  * direct mapping of the BSD socket API in a portable GObject based API.
51  * It supports both the UNIX socket implementations and winsock2 on Windows.
52  * 
53  * #GSocket is the platform independent base upon which the higher level
54  * network primitives are based. Applications are not typically meant to
55  * use it directly, but rather through classes like #GSocketClient,
56  * #GSocketService and #GSocketConnection. However there may be cases where
57  * direct use of #GSocket is useful.
58  * 
59  * #GSocket implements the #GInitable interface, so if it is manually constructed
60  * by e.g. g_object_new() you must call g_initable_init() and check the
61  * results before using the object. This is done automatically in
62  * g_socket_new() and g_socket_new_from_fd(), so these functions can return
63  * %NULL.
64  * 
65  * Sockets operate in two general modes, blocking or non-blocking. When
66  * in blocking mode all operations (which don’t take an explicit blocking
67  * parameter) block until the requested operation
68  * is finished or there is an error. In non-blocking mode all calls that
69  * would block return immediately with a %G_IO_ERROR_WOULD_BLOCK error.
70  * To know when a call would successfully run you can call g_socket_condition_check(),
71  * or g_socket_condition_wait(). You can also use g_socket_create_source() and
72  * attach it to a #GMainContext to get callbacks when I/O is possible.
73  * Note that all sockets are always set to non blocking mode in the system, and
74  * blocking mode is emulated in GSocket.
75  * 
76  * When working in non-blocking mode applications should always be able to
77  * handle getting a %G_IO_ERROR_WOULD_BLOCK error even when some other
78  * function said that I/O was possible. This can easily happen in case
79  * of a race condition in the application, but it can also happen for other
80  * reasons. For instance, on Windows a socket is always seen as writable
81  * until a write returns %G_IO_ERROR_WOULD_BLOCK.
82  * 
83  * #GSockets can be either connection oriented or datagram based.
84  * For connection oriented types you must first establish a connection by
85  * either connecting to an address or accepting a connection from another
86  * address. For connectionless socket types the target/source address is
87  * specified or received in each I/O operation.
88  * 
89  * All socket file descriptors are set to be close-on-exec.
90  * 
91  * Note that creating a #GSocket causes the signal %SIGPIPE to be
92  * ignored for the remainder of the program. If you are writing a
93  * command-line utility that uses #GSocket, you may need to take into
94  * account the fact that your program will not automatically be killed
95  * if it tries to write to %stdout after it has been closed.
96  * 
97  * Like most other APIs in GLib, #GSocket is not inherently thread safe. To use
98  * a #GSocket concurrently from multiple threads, you must implement your own
99  * locking.
100  *

1517 	 *
1518 	 * If @address is %NULL then the message is sent to the default receiver
1519 	 * (set by g_socket_connect()).
1520 	 *
1521 	 * @vectors must point to an array of #GOutputVector structs and
1522 	 * @num_vectors must be the length of this array. (If @num_vectors is -1,
1523 	 * then @vectors is assumed to be terminated by a #GOutputVector with a
1524 	 * %NULL buffer pointer.) The #GOutputVector structs describe the buffers
1525 	 * that the sent data will be gathered from. Using multiple
1526 	 * #GOutputVectors is more memory-efficient than manually copying
1527 	 * data from multiple sources into a single buffer, and more
1528 	 * network-efficient than making multiple calls to g_socket_send().
1529 	 *
1530 	 * @messages, if non-%NULL, is taken to point to an array of @num_messages
1531 	 * #GSocketControlMessage instances. These correspond to the control
1532 	 * messages to be sent on the socket.
1533 	 * If @num_messages is -1 then @messages is treated as a %NULL-terminated
1534 	 * array.
1535 	 *
1536 	 * @flags modify how the message is sent. The commonly available arguments
1537 	 * for this are available in the #GSocketMsgFlags enum, but the
1538 	 * values there are the same as the system values, and the flags
1539 	 * are passed in as-is, so you can pass in system-specific flags too.
1540 	 *
1541 	 * If the socket is in blocking mode the call will block until there is
1542 	 * space for the data in the socket queue. If there is no space available
1543 	 * and the socket is in non-blocking mode a %G_IO_ERROR_WOULD_BLOCK error
1544 	 * will be returned. To be notified when space is available, wait for the
1545 	 * %G_IO_OUT condition. Note though that you may still receive
1546 	 * %G_IO_ERROR_WOULD_BLOCK from g_socket_send() even if you were previously
1547 	 * notified of a %G_IO_OUT condition. (On Windows in particular, this is
1548 	 * very common due to the way the underlying APIs work.)
1549 	 *
1550 	 * On error -1 is returned and @error is set accordingly.
