Detailed Description



creates a ServerSocket on this port
 UServerSocket* se = new UServerSocket(666);

foo() will be called each time the servsoket receives a connection
request. Note that the servsocket is given as an argument to foo()
 se->onInput(ucall(se, foo));

 void foo(UServerSocket* se) {
accepts the connection an returns the corresponding socket
     USocket* so = se->accept();

Member Function Documentation

USocket * ubit::UServerSocket::accept (  )  [virtual]

listens for a connection to be made and accepts it.

This method blocks until a connection is made. It is typically called in a callback function: see onInput() and class UServerSocket

Note: accept() calls createSocket() to create the new socket. By default this functions returns {new USocket}. It can be redefined by UServerSocket subclasses to create appropriate socket objets.

void ubit::UServerSocket::onInput ( UCall  )  [virtual]

adds a callback that is fired when data is received on the server socket.

accept() is typically called in such a callback
