EPICS V4 question

[Mark Rivers <rivers@cars.uchicago.edu>]

I have some EPICS V4 client code that basically does the following:

 

class epicsShareClass pvaDriver : public ADDriver,

        public virtual epics::pvAccess::ChannelRequester,

        public virtual epics::pvData::MonitorRequester

 

…

 

    try

    {

        ClientFactory::start();

        m_provider = getChannelProviderRegistry()->getProvider("pva");

        m_channel = m_provider->createChannel(m_pvName, m_thisPtr, m_priority);

        m_pvRequest = CreateRequest::create()->createRequest(m_request);

        m_monitor = m_channel->createMonitor(m_thisPtr, m_pvRequest);

    }

    catch (exception &ex)

    {

…

    }

 

The monitorConnect() and monitorEvent() methods are being called as expected, and everything is working.

 

Now I want to extend the code to allow the current channel to be disconnected, and call m_provider->createChannel() to a different channel.  What do I need to do for this?  I found that if I just call m_provider->createChannel with a different p_pvName it does not throw an exception, but it appears to simply stay connected to the existing channel.

 

Thanks,

Mark
