FWD: Record referencing inside device support

[Allan Serra Braga Bugyi <allan.bugyi@lnls.br>]

Hi Andrew,

In my mind, the C code will be a file containing all the functions to connect, request data stream/polling, run equipment adjustment routines, change properties and close connection. All of this is provided by the manufacturer .so library (which I'm adding to the LIBS target of the IOC's Makefile). So, the IOC will carry everything within itself needed to control the equipment.

What I have in mind is to add this .cpp file to the SRCS target of the IOC's Makefile, and to call all of these functions using subroutine records.

The equipment is an interferometer from SmarAct, called PicoScale.

Best,
Allan S. B. Bugyi.

What is "your C code" — where is it running and what calls it? You need
to describe what you're doing it a bit more detail for us to be able to
help you as the answers will be different for different circumstances...
