Subject:	[AsynDriver] getAddress and callbacks

Hello Mark,

Sorry to bother you, I have a question regarding the usage of this function:

I have a use case where it is useful to override asynPortDriver::getAddress() to get a custom reason and address.

These values are chosen previously by drvUserCreate(), and stored in pasynUser->drvUser and pasynUser->reason.

This seems to work well for gets and puts, but not when a callback for for a "I/O Intr" record is executed.

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

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

Is there a way to make the callbacks also use the custom asynPortDriver::getAddress() value?

Thank you in advance,

Joao
