Hi Rus,
If you go to http://www.zentropix.com/ and click downloads, you'll see
rtai_rtl_fifos-05.tar.gz. This is a portable version of the RTAI
newfifos package. I have added a test to make sure that a non-blocking
read on a fifo with no data does not block (after building run
./regression). I've tested this with RTAI 1.3 and this behaves as
expected (immediate return with EAGAIN). Please take a look and let me
know if I have missunderstood anything, or if your results are
different.
Regards, Stuart
