Hello Eric,
Based on our experiences, I would recommend directly using the CA libraries.
The EPICS Web Site is right.
My 2 cents:
EZCA is only noticeably easier than CA for very simple tasks.
As soon as you want to do something real, EZCA will get as complicated
as CA. (I should say "as easy as CA".)
EZCA has shown some problems in the past: mostly with long-running
real-life applications.
Last, definitely not least: When you have a problem and contact the
brave and supportive people at tech-talk, there will be a tendency to
blame it on EZCA and considerably less enthusiasm to get into the
details with you.
Hope this helps, (I really do!)

Hi,
We are presently considering the use of the Easy CA interface for
future needs. A first but very simple test works fine and was quickly
performed but we are quite frightened by the warnings within the Epics
Web site :
"In practice though if you have problems getting code to work that
uses EZCA or if you get unexplained failures or crashes, you will get
less help from the EPICS community in debugging the issue than you
will if you use the native CA API. The CA API is not hard to use, and
EZCA is not maintained as aggressively as the underlying CA library."
So before going further, we would like to know your experience and
feeling when considering the use of the E-Z CA interface not only for
small tests but for bigger developments having to be reliable and to
be used for many years. What would you advice us to do : use the
simple E-Z CA package or prefer the more complex (but better
maintained ?) Channel Access library ?
Thanks a lot for any comment
