[ECOS] Pipes in eCos

[ECOS] Pipes in eCos

[Venkateswara Rao L.]

Hi all,

	It seams eCos does not support pipes, is there anything
equivalent to that?

Warm Regards,
L.Venkateswara Rao.

eCos doesn't have processes, so pipes wouldn't be particularly useful.
You could certainly create a pipe emulation mechanism, but what is it
that you're trying to do?

Take a look at the thread:

http://www.cygwin.com/ml/ecos-patches/2004-12/msg00034.html

It was decided not to include it because it does not really follow the
eCos way of doing things, but that should not stop you from using it
is you want.

Hi Andrew,

Out of curiosity, how does that pipe/pty implementation fall short for 
eCos? I've been thinking of using it to get a select()-able file 
descriptor for inter-thread communication.

Are there improvements that could be made to make it fit into eCos 
better? I'd be willing to give it a try. Otherwise I'll just use my 
version quietly.

There was discussion at the time. What does the archive say? It is
something like two years ago, so i don't remember myself.

Chris

My requirement is to do some communication among threads .I can use MSGQ
for this. But I need to use select with the communication mechanism. As
using select is proving to be quite generic for my requirement. I've to
put additional infrastructure if i use msgqs.
