FAQ

• What’s the best way for an application to determine the name/slot of the currently active controller in the cluster?

The relevant API is "clCpmSlotGet". Example code is as follows:

#include <clCpmExtApi.h>
ClRcT masterNodeGet(void)
{
    ClIocNodeAddressT node = 0;
    ClRcT rc = clCpmMasterAddressGet(&node);
    if(node)
    {
        ClCpmSlotInfoT slotInfo = {.slotId = node } ;
        rc = clCpmSlotGet(CL_CPM_SLOT_ID, &slotInfo);
        if(rc == CL_OK)
            clLogNotice("MASTER", "GET", " Node name [%.*s]",
                        slotInfo.nodeName.length, slotInfo.nodeName.value);
    }
    return rc;
}
