43/*! \class QNativeSocketEngine-
44 \internal-
45-
46 \brief The QNativeSocketEngine class provides low level access to a socket.-
47-
48 \reentrant-
49 \ingroup network-
50 \inmodule QtNetwork-
51-
52 QtSocketLayer provides basic socket functionality provided by the-
53 operating system. It also keeps track of what state the socket is-
54 in, and which errors that occur.-
55-
56 The classes QTcpSocket, QUdpSocket and QTcpServer provide a-
57 higher level API, and are in general more useful for the common-
58 application.-
59-
60 There are two main ways of initializing the a QNativeSocketEngine; either-
61 create a new socket by passing the socket type (TcpSocket or-
62 UdpSocket) and network layer protocol (IPv4Protocol or-
63 IPv6Protocol) to initialize(), or pass an existing socket-
64 descriptor and have QNativeSocketEngine determine the type and protocol-
65 itself. The native socket descriptor can later be fetched by-
66 calling socketDescriptor(). The socket is made non-blocking, but-
67 blocking behavior can still be achieved by calling waitForRead()-
68 and waitForWrite(). isValid() can be called to check if the socket-
69 has been successfully initialized and is ready to use.-
70-
71 To connect to a host, determine its address and pass this and the-
72 port number to connectToHost(). The socket can then be used as a-
73 TCP or UDP client. Otherwise; bind(), listen() and accept() are-
74 used to have the socket function as a TCP or UDP server. Call-
75 close() to close the socket.-
76-
77 bytesAvailable() is called to determine how much data is available-
78 for reading. read() and write() are used by both TCP and UDP-
79 clients to exchange data with the connected peer. UDP clients can-
80 also call hasMoreDatagrams(), nextDatagramSize(),-
81 readDatagram(), and writeDatagram().-
82-
83 Call state() to determine the state of the socket, for-
84 example, ListeningState or ConnectedState. socketType() tells-
85 whether the socket is a TCP socket or a UDP socket, or if the-
86 socket type is unknown. protocol() is used to determine the-
87 socket's network layer protocol.-
88-
89 localAddress(), localPort() are called to find the address and-
90 port that are currently bound to the socket. If the socket is-
91 connected, peerAddress() and peerPort() determine the address and-
92 port of the connected peer.-
93-
94 Finally, if any function should fail, error() and-
95 errorString() can be called to determine the cause of the error.-
96*/-
97-
98/*!-
99 \enum QAbstractSocketEngine::PacketHeaderOption-
100-
101 Specifies which fields in the IP packet header are desired in the call to-
102 readDatagram().-
103-
104 \value WantNone caller isn't interested in the packet metadata-
105 \value WantDatagramSender caller wants the sender address and port number-
106 \value WantDatagramDestination caller wants the packet's destination address and port number-
107 (this option is useful to distinguish multicast packets from unicast)-
108 \value WantDatagramHopLimit caller wants the packet's remaining hop limit or time to live-
109 (this option is useful in IPv4 multicasting, where the TTL is used-
110 to indicate the realm)-
111 \value WantAll this is a catch-all value to indicate the caller is-
112 interested in all the available information-
