About
-----

This module contains two parts: 

- A generic (`EPICS`_-independent) library implementing one- and
  two-dimensional interpolation tables, including procedures to load and store
  them from a file system.
- An `EPICS`_ record type specifically designed to make it easy to do
  conversion via interpolation table and other means. The cvtRecord uses the
  csm library to achieve conversion via tables.

The functions *thread safe*, when you compute a function value and the
function definition is changed in parallel, is is ensured that the function
computation always uses a consistent function definition.
