Detailed Description

A TCP/IP client socket.

Deprecated:
You can connect this socket to any Internet address.

This class is deprecated and will be removed in the future. For new programs, please use KExtendedSocket class.

The socket gives you three signals: When ready for reading, ready for writing or if the connection is broken. Using socket() you get a file descriptor which you can use with the usual UNIX function like write() or read(). If you have already such a socket identifier you can construct a KSocket on this identifier.

If socket() delivers a value of -1 or less, the connection was not successful.

Constructor & Destructor Documentation

KSocket::KSocket int  _sock  ) 
 

Constructs a KSocket with the provided file descriptor.

Parameters:
_sock The file descriptor to use.

Definition at line 101 of file ksock.cpp.

References KSocks::self().

KSocket::KSocket const char *  _host,
unsigned short int  _port,
int  timeOut = 30
 

Creates a socket and connects to a host.

Parameters:
_host The remote host to which to connect.
_port The port on the remote host.
timeOut The number of seconds waiting for connect (default 30).

Definition at line 115 of file ksock.cpp.

KSocket::KSocket const char *  _path  ) 
 

Connects to a UNIX domain socket.

Parameters:
_path The filename of the socket.

Definition at line 121 of file ksock.cpp.

KSocket::~KSocket  )  [virtual]
 

Destructor.

Closes the socket if it is still open.

Definition at line 260 of file ksock.cpp.


Member Function Documentation

int KSocket::socket  )  const [inline]
 

Returns a file descriptor for this socket.

Returns:
the file descriptor, or -1 when an error occurred.

Definition at line 117 of file ksock.h.

void KSocket::enableRead bool  enable  ) 
 

Enables the socket for reading.

If you enable read mode, the socket will emit the signal readEvent() whenever there is something to read out of this socket.

Parameters:
enable true to enable reading signals

Definition at line 127 of file ksock.cpp.

References slotRead().

void KSocket::enableWrite bool  enable  ) 
 

Enables the socket for writing.

If you enable write mode, the socket will emit the signal writeEvent() whenever the socket is ready for writing.

Warning: If you forget to call enableWrite(false) when you are not ready to send data, you will get lots of writeEvent() signals, in the order of thousands a second !

Parameters:
enable true to enable writing signals

Definition at line 143 of file ksock.cpp.

References slotWrite().

void KSocket::readEvent KSocket s  )  [signal]
 

Data has arrived for reading.

This signal will only be raised if enableRead( true ) was called first.

Parameters:
s the KSocket that triggered the event

Referenced by slotRead().

void KSocket::writeEvent KSocket s  )  [signal]
 

Socket is ready for writing.

This signal will only be raised if enableWrite( true ) was called first.

Warning: If you forget to call enableWrite(false) when you are not ready to send data, you will get lots of writeEvent() signals, in the order of thousands a second !

Parameters:
s the KSocket that triggered the event

Referenced by slotWrite().

void KSocket::closeEvent KSocket s  )  [signal]
 

Raised when the connection is broken.

Parameters:
s the KSocket that triggered the event

Referenced by slotRead().

void KSocket::slotWrite int  x  )  [slot]
 

Connected to the writeNotifier.

Called when the socket is ready for writing.

Parameters:
x ignored

Definition at line 171 of file ksock.cpp.

Referenced by enableWrite().

void KSocket::slotRead int  x  )  [slot]
 

Connected to the readNotifier.

Called when the socket is ready for reading.

Parameters:
x ignored
