RE: [dsdp-tcf-dev] Custom TCF Service
|
Hi Florian,
A simple approach to implement "read" command would be
to call read(), then send a reply that contains error report, end-of-file flag
and data. Data can be encoded with json_write_binary() or formatted into text and sent with
json_write_string()
- your choice. Clients would
need to send multiple "read" commands to read all
data.
Since read() function is blocking, much better approach is to
use asynchronous I/O instead of calling read() directly from command handler. It
would allow agent to process other commands while waiting for read() to return.
You can see an example of asynchronous implementation of "read" command in
filesystem.c

Eugene
Hello,
I'm currently creating my new TCF service. On TCF, I've
added a list of trivial commands manipulating the /dev/entry ioctls (GETSIZE,
SETSIZE) and I'm now trying to implement the "read" action.
Reading the
/dev/entry results in the obtention of binary data that I have to format into
text (no problem) and send line by line to Eclipse. My problem is that I don't
know how to transfer these lines of text (do I have to use the "intermediate"
type of result ?) and how to receive them on the Eclipse side. Do you have any
tip to do so ? (I hope I was clear enough for you to
understand)

I use RSE to propose a cohesive interface with the target
(custom terminal subsystem, custom TCF files subsystem, custom
actions...).
Ideally, I was thinking about a popup menu action (on a RSE
connection) which would fetch data from the target (text, line by
line).
That wouldn't bother me to avoid the creation of a subsystem just
for this particular action.

Hi
Florian,
It
depends on what you want to achieve. You can, but don't have to create RSE
subsystem for the TCF service. TCF is usable without
RSE.

Eugene.
Hi,
My new goal is to extend the TCF agent by adding a
custom service.
That service should allow the user to open a /dev/ entry
on the target, and getting its data (through the channel), in order to
display it in Eclipse.
I've been studying the daytime example, but i'm a
little confused about the Eclipse-side of the problem.
Do I have to
create a new RSE subsystem relative to this service
?
Regards,
Florian
