Hi Joao,

 

Perhaps I spoke too soon.  It seems like it might work to replace this in asynPortDriver.

 

        pasynManager->getAddr(pInterrupt->pasynUser, &address);

 

with this

 

        this->getAddress(pInterrupt->pasynUser, &address);

 

Why don’t you try that and see if it works?  If asynPortDriver::getAddress has not been overridden then this should not affect the existing behavior.

Hi Joao,

 

Ø  In those cases, the IOC will get the address from "pasynManager->getAddr()", and not from getAddress(), which breaks the program.

Ø  (for ex. in paramList::octetCallback())

 

The callbacks are traversing a linked list of clients that have registered for callbacks.  This is typically asyn device support, but it is not limited to that.  That linked list is created outside of asynPortDriver by asynManager when each client registers for callbacks.   For example, this is the abbreviated code in devAsynInt32.c

 

    pasynUser = pasynManager->createAsynUser(processCallback, 0);

    pPvt->pasynUser = pasynUser;

    status = pasynEpicsUtils->parseLink(pasynUser, plink,

               &pPvt->portName, &pPvt->addr, &pPvt->userParam);

    status = pasynManager->connectDevice(pasynUser, pPvt->portName, pPvt->addr);

    status = pPvt->pint32->registerInterruptUser(

               pPvt->int32Pvt,pPvt->pasynUser,

               pPvt->interruptCallback,pPvt,&pPvt->registrarPvt);

 

So that pPvt->pasynUser has been connected to a particular port and address, typically specified in the OUT in INP link in the record.  The asynPortDriver callback functions are retrieving the address stored in that pasynUser in the linked list node via pasynManager->get_addr().

 

    pnode = (interruptNode *)ellFirst(pclientList);

    while (pnode) {

        asynInt32Interrupt *pInterrupt = (asynInt32Interrupt *) pnode->drvPvt;

        pasynManager->getAddr(pInterrupt->pasynUser, &address);

        /* If this is not a multi-device then address is -1, change to 0 */

        if (address == -1) address = 0;

        if ((command == pInterrupt->pasynUser->reason) &&

            (address == addr)) {

 

I don’t see how it could have access to the address that your getAddress() method is generating?
