Used to wait for pending connection requests. | |
virtual | ~DCCPSocket () |
Use base socket handler for ending this socket. |
Both error recovery and flow control operate transparently for a DCCP socket connection. The DCCP socket base class is used both for client connections and to bind a DCCP "server" for accepting DCCP streams.
An implicit and unique DCCPSocket object exists in Common C++ to represent a bound DCCP socket acting as a "server" for receiving connection requests. This class is not part of DCCPStream because such objects normally perform no physical I/O (read or write operations) other than to specify a listen backlog queue and perform "accept" operations for pending connections. The Common C++ DCCPSocket offers a Peek method to examine where the next pending connection is coming from, and a Reject method to flush the next request from the queue without having to create a session.
The DCCPSocket also supports a "OnAccept" method which can be called when a DCCPStream related object is created from a DCCPSocket. By creating a DCCPStream from a DCCPSocket, an accept operation automatically occurs, and the DCCPSocket can then still reject the client connection through the return status of it's OnAccept method.

A DCCP "server" is created as a DCCP socket that is bound to a hardware address and port number on the local machine and that has a backlog queue to listen for remote connection requests. If the server cannot be created, an exception is thrown.

Create a named dccp socket by service and/or interface id. For IPV4 we use [host:]svc or [host/]svc for the string. If we have getaddrinfo, we use that to obtain the addr to bind for.

A method to call in a derived DCCPSocket class that is acting as a server when a connection request is being accepted. The server can implement protocol specific rules to exclude the remote socket from being accepted by returning false. The Peek method can also be used for this purpose.
