RE: Record Parameters in Asyn Port Driver

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

Hi Igor,

The idea of asyn port drivers is that they don't know anything about the EPICS records.  They only know about the standard asyn interfaces (asynInt32, asynUInt32Digital, asynOctet, etc.).  The device-independent device support in asyn/devEpics is the only code that knows about the record fields.

Can you please explain what you want your driver to do, and I can probably tell you how to do it without your asyn port driver needing to know anything about the record fields.

Mark

Subject: Record Parameters in Asyn Port Driver

Hello everyone,

I'm developing an IOC using Asyn Port Driver, and I couldn't find out how to get some record parameters in the device support code (cpp file).

I need to get the INP and OUT parameters (port,addres,mask,timeout,...) and also NOBT for mbbi and mbbo records. As well as parameters for ai and ao records (EGUF, EGUL, etc).

Can anyone help me?
