示例1: ErrorMessage
//blocking call
Message *MessageEndpoint::PopMessage(Ticket &ticket, int timeout)
{
Message *ret;
MessageQueue *queue = m_queues.GetByOurSerial(ticket.m_ourSerialNum);
if(queue == NULL)
{
//Tried to read from a queue, but it didn't exist. We must have closed it, and then tried reading.
// This is a protocol error
return new ErrorMessage(ERROR_PROTOCOL_MISTAKE);
}
//TODO: This is not quite right. We should keep returning valid messages as long as
// we have them. We should ask the MessageQueue for a new message (maybe peek?)
// and only return a shutdown message if one doesn't exist there.
//If we're shut down, then return a shutdown message
{
Lock shutdownLock(&m_isShutdownMutex);
if(m_isShutDown)
{
return new ErrorMessage(ERROR_SOCKET_CLOSED);
}
}
ret = queue->PopMessage(timeout);
if(ret->m_messageType == ERROR_MESSAGE)
{

if(error->m_errorType == ERROR_TIMEOUT)
