Subject: RE: What is all I need to know to write a CA protocal?

Hello,

When I was writing a CA library in C# and I was strongly relying on the
cosylab epics protocol specification at:
http://epics.cosylab.com/cosyjava/JCA-Common/Documentation/CAproto.html

Also you may be able to read something out of the source code of the
library, which you find at:
http://gfa-it.web.psi.ch/epicsSharp/

At the moment I am writing an developer documentation for the library,
which does also contain some basic stuff about the protocol, and if you
are interested I'll send it to you, as soon as it is finished.

But I do also want to express my doubts that it is possible to do a CA
library with ActionScript. I am not really deep in ActionScript, but as
far as I do know, it's missing to much of the network support to be able
to do such a implementation.

Kind regards,
Christoph Seiler

Subject: What is all I need to know to write a CA protocal?

Hi,

I'm planning to write an ActionScript library for CA, but I know little
about the network. Could any of you give me some advice about which
files in EPICS I should read?

It's all started because I'm not totally satisfied with EDM. It's ugly
(sorry to say that) and not platform-independent. I've tried some flash
recently and felt amazing, so I want to use ActionScript and Flex SDK to
make a beautiful and cross-platform interface.

By the way, compiling EDM is not an interesting trip. The open()
function should have three parameters but the one in utility.cc has only
two so I have to add the "mode" parameter: 0644, I'm not sure if it's
right, maybe 755 is better?
Anyway, on a 64bit Ubuntu with gcc version 4.3.3, I can't link
correctly, linking to libXm, libXp, blahblah.... reports "bad symbols"
errors, but I guess it's the compiler's problem.

Best Regards
