ost::DCCPSocket::DCCPSocket(constIPV4Address&bind,tpport_tport,unsignedbacklog=5)
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.
Parametersbind local ip address or interface to use.
port number to bind socket under.
backlog size of connection request queue.
ost::DCCPSocket::DCCPSocket(constIPV6Address&bind,tpport_tport,unsignedbacklog=5)ost::DCCPSocket::DCCPSocket(constchar*name,Familyfamily=IPV4,unsignedbacklog=5)
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.
Parametersname of host interface and service port to bind.
backlog size of connection request queue.
ost::DCCPSocket::DCCPSocket(Familyfamily=IPV4)
Create an unconnected ephemeral DCCP client socket.
ost::DCCPSocket::DCCPSocket(DCCPSocket&server,timeout_ttimeout=0)
Create a server session by accepting a DCCP Socket.
virtualost::DCCPSocket::~DCCPSocket()[virtual]
Use base socket handler for ending this socket.
Detailed Description
DCCP sockets are used for stream based connected sessions between two sockets.
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.

virtualboolost::DCCPSocket::onAccept(constIPV4Host&ia,tpport_tport)[virtual]
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.
Returns
true if client should be accepted.
Parametersia internet host address of the client.
port number of the client.
