RWSocketListener() WhoShouldClose

#include <rw/network/RWSocketListener.h>

Waits on a specified socket address for incoming connections. Connections are obtained as RWSocketPortals.

enum WhoShouldClose { Portal, Application };

Indicates who should close the socket.

RWSocketListener();

Creates an uninitialized socket listener. Self needs to be initialized using listen() before it can be used.

RWSocketListener(const RWSockAddrBase& address, 
                  int backlog=5);

Sets up a listener on the address indicated, and sets up a queue to wait for connections. The backlog parameter specifies the number of incoming connection requests that the protocol software enqueues while a connection is being processed.

RWSocketListener(const RWSocket& socket, 
                 WhoShouldClose who=Portal);

Creates a listening portal to the communications channel, where socket is the socket doing the listening. Using this constructor is the only way to create a socket that is not closed automatically when portals are no longer using it.

~RWSocketListener();

Destructor.

RWSocketPortal
accept(RWSockAddr* addr=0) const;

Receives the next waiting connection. The address of the connecting client will be stored in the RWSockAddr referenced by addr.

RWSocketPortal
operator()(RWSockAddr* addr=0) const;

Receives the next waiting connection. The address of the connecting client will be stored in the RWSockAddr referenced by addr.

RWSocket
getSocket() const;

Obtains a reference to the underlying socket.

void
listen(const RWSockAddrBase& address, int backlog=5);

Binds the listener to the address indicated, and sets up a queue to wait for connections. The backlog parameter specifies the number of incoming connection requests that the protocol software enqueues while a connection is being processed.
