Re: [rtl] Two modules, one rt-fifo

[Stuart Hughes <sehughes@zentropix.com>]

This functionality is already implemented in the new rtai_rtl_fifos
packages recently posted on the newsgroup and available from
http://www.rtai.org/

It allows the following comms:

rt_task <-> rt_task
rt_task <-> linux process

A problem with the (user) read call has been fixed to mirror the POSIX
read semantics.  So now it should be compatible with the RTLinux API.

NOTE: the updated package with this fix should appear on the above site
in the next couple of days.

This module is fairly new, so please report any bugs you find.

Regards, Stuart
