A TCP/IP client socket. You can connect this socket to any internet address.
The socket gives you three signals: When ready for reading/writing or if the connection is broken. Using socket() you get a file descriptor which you can use with usual unix commands 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 had no success.
KSocket ( int _sock ) : sock(_sock), domain(0), readNotifier(0), writeNotifier(0) |
Create a KSocket with the provided file descriptor.
Parameters:
_sock | the file descriptor to use. |
KSocket ( const char *_host, unsigned short int _port ) |
Create a socket and connect to a host.
Parameters:
_host | the remote host to which to connect. |
_port | the port on the remote host. |
KSocket ( const char *_path ) |
Connects to a UNIX domain socket.
Parameters:
_path | the filename of the socket |
~KSocket () |
Destructor. Closes the socket if it is still open.
int socket () |
Returns a file descriptor for this socket.
void enableRead ( bool ) |
Enable 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.
void enableWrite ( bool ) |
Enable the socket for writing.
If you enable write mode, the socket will emit the signal writeEvent whenever the socket is ready for writing.
unsigned long getAddr () |
Return address.
void readEvent ( KSocket * ) |
Data has arrived for reading.
This signal will only be raised if enableRead( TRUE ) was called first.
void writeEvent ( KSocket * ) |
Socket is ready for writing.
This signal will only be raised if enableWrite( TRUE ) was called first.
void closeEvent ( KSocket * ) |
Raised when the connection is broken.
void slotWrite ( int ) |
Connected to the writeNotifier.
void slotRead ( int ) |
Connected to the readNotifier.
int sock |
The file descriptor for this socket. sock may be -1. This indicates that it is not connected.
