Detailed Description

Monitors a port for incoming TCP/IP connections.

Deprecated:

Please use the more powerful KExtendedSocket class.

You can use a KServerSocket to listen on a port for incoming connections. When a connection arrived in the port, a KSocket is created and the signal accepted is raised. Make sure you always connect to this signal. If you don't the ServerSocket will create new KSocket's and no one will delete them!

If socket() is -1 or less the socket was not created properly.

Constructor & Destructor Documentation

KServerSocket::KServerSocket (  unsigned short int    _port, bool    _bind = true )

Constructor. Parameters: _port  the port number to monitor for incoming connections. _bind  if false you need to call bindAndListen yourself. This gives you the opportunity to set options on the socket.

KServerSocket::KServerSocket (  const char *    _path, bool    _bind = true )

Creates a UNIX domain server socket. Parameters: _path  path used for the socket. _bind  if false you need to call bindAndListen yourself. This gives you the opportunity to set options on the socket.

virtual KServerSocket::~KServerSocket (    )  [virtual]

Destructor. Closes the socket if it was not already closed.

Member Function Documentation

void KServerSocket::accepted (  KSocket *    s )  [signal]

A connection has been accepted. It is your task to delete the KSocket if it is no longer needed. WARNING: this signal is always emitted, even if you don't connect anything to it. That would mean memory loss, because the KSockets created go to oblivion. Parameters: s  the socket that accepted

bool KServerSocket::bindAndListen (    )

Binds the socket and start listening. This should only be called once when the constructor was called with _bind false. On error the socket will be closed. Returns: true on success. false on error.

unsigned short int KServerSocket::port (    )

Returns the port number which is being monitored. Returns: the port number

virtual void KServerSocket::slotAccept (  int    )  [virtual, slot]

Called when someone connected to our port.

int KServerSocket::socket (    )  const [inline]

Returns the file descriptor associated with the socket. Returns: the file descriptor, -1 when an error occured during construction or bindAndListen Definition at line 281 of file ksock.h. References sock.
