The QServerSocket class provides a TCP-based server.
network.
This class is a convenience class for accepting incoming TCP connections. You can specify the port or have QServerSocket pick one, and listen on just one address or on all the machine's addresses.
Using the API is very simple: subclass QServerSocket, call the constructor of your choice, and implement newConnection() to handle new incoming connections. There is nothing more to do.
(Note that due to lack of support in the underlying APIs, QServerSocket cannot accept or reject connections conditionally.)
| QServerSocket::QServerSocket | ( | Q_UINT16 | port, |
| int | backlog = 1, |
||
| QObject * | parent = 0, |
||
| const char * | name = 0 |
||
| ) |
Creates a server socket object, that will serve the given port on all the addresses of this host. If port is 0, QServerSocket will pick a suitable port in a system-dependent manner. Use backlog to specify how many pending connections the server can have.
The parent and name arguments are passed on to the QObject constructor.
| QServerSocket::QServerSocket | ( | const QHostAddress & | address, |
| Q_UINT16 | port, | ||
| int | backlog = 1, |
||
| QObject * | parent = 0, |
||
| const char * | name = 0 |
||
| ) |
Creates a server socket object, that will serve the given port only on the given address. Use backlog to specify how many pending connections the server can have.
The parent and name arguments are passed on to the QObject constructor.
| QServerSocket::QServerSocket | ( | QObject * | parent = 0, |
| const char * | name = 0 |
||
| ) |
Construct an empty server socket.
This constructor, in combination with setSocket(), allows us to use the QServerSocket class as a wrapper for other socket types (e.g. Unix Domain Sockets under Unix).
The parent and name arguments are passed on to the QObject constructor.
| QServerSocket::~QServerSocket | ( | ) | [virtual] |
Destroys the socket.
This causes any backlogged connections (connections that have reached the host, but not yet been completely set up by calling QSocketDevice::accept()) to be severed.
Existing connections continue to exist; this only affects the acceptance of new connections.

| int | backlog = 1, |

| QObject * | parent = 0, |

| const char * | name = 0 |

| virtual QServerSocket::~QServerSocket | ( | ) | [virtual] |
| QHostAddress QServerSocket::address | ( | ) | const |
Returns the address on which this object listens, or 0.0.0.0 if this object listens on more than one address. ok() must be TRUE before calling this function.
| QHostAddress QServerSocket::address | ( | ) | const |
| void QServerSocket::newConnection | ( | int | socket | ) | [pure virtual] |
This pure virtual function is responsible for setting up a new incoming connection. socket is the fd (file descriptor) for the newly accepted connection.
| virtual void QServerSocket::newConnection | ( | int | socket | ) | [pure virtual] |
| bool QServerSocket::ok | ( | ) | const |
Returns TRUE if the construction succeeded; otherwise returns FALSE.
| bool QServerSocket::ok | ( | ) | const |
| Q_UINT16 QServerSocket::port | ( | ) | const |
| Q_UINT16 QServerSocket::port | ( | ) | const |
Returns the port number on which this server socket listens. This is always non-zero; if you specify 0 in the constructor, QServerSocket will pick a non-zero port itself. ok() must be TRUE before calling this function.
| void QServerSocket::setSocket | ( | int | socket | ) | [virtual] |
Sets the socket to use socket. bind() and listen() should already have been called for socket.
This allows us to use the QServerSocket class as a wrapper for other socket types (e.g. Unix Domain Sockets).
| virtual void QServerSocket::setSocket | ( | int | socket | ) | [virtual] |
| int QServerSocket::socket | ( | ) | const |
| int QServerSocket::socket | ( | ) | const |
Returns the operating system socket.
| QSocketDevice* QServerSocket::socketDevice | ( | ) | [protected] |
| QSocketDevice * QServerSocket::socketDevice | ( | ) | [protected] |
Returns a pointer to the internal socket device. The returned pointer is 0 if there is no connection or pending connection.
There is normally no need to manipulate the socket device directly since this class does all the necessary setup for most client or server socket applications.
