In this simulation, we use the rtlinux POSIX-like API for threads,
timing, and writing-to / reading-from real-time FIFOs. It looks like
the xeno_posix API will allow me to port the thread and timing code with
very few (if any) changes. There does not appear to be a kernel-space
version of read and write for use on xenomai pipes. Am I missing
something?
For what side, RT or non-RT? Or what service (function name) is missing
precisely?
RT-Linux has a mostly POSIX interface to rt-fifos. You must create/delete them
using the non-standard rtf_create/rtf_destroy, but after that, you can open,
close, read, and write them using a file descriptor. I was wondering if this
mapping exists for the real-time Xenomai POSIX API. I am specifically asking
about kernel-space right now, but I would also like to know if this sort of
thing is supported from user-space real-time as well.
