Member Function Documentation

void epics::pvAccess::ServerResponseHandler::handleResponse ( osiSockAddr *  responseFrom, Transport::shared_pointer const &  transport, epics::pvData::int8  version, epics::pvData::int8  command, std::size_t  payloadSize, epics::pvData::ByteBuffer *  payloadBuffer  )

virtual

Handle response.

Parameters

[in]	responseFrom	remote address of the responder, 0 if unknown.
[in]	transport	response source transport.
[in]	version	message version.
[in]	payloadSize	size of this message data available in the payloadBuffer.
[in]	payloadBuffer	message payload data. Note that this might not be the only message in the buffer. Code must not manipulate buffer.
