Thanks.Looking forward to your replay.


In fact, we lack an example driver. However, the usage is analoguous to
the kernel's UIO framework, and details a documented in
https://gitlab.denx.de/Xenomai/xenomai/-/blob/master/include/cobalt/kernel/rtdm/udd.h


Some time ago, Philippe posted a simple UDD driver:

Ah, sorry, that's a driver example but I also remember a user-space
example program. Start digging now...


TIA! If someone could create the content for wiki entry, I would add
that under "Programming".

OK, I can prepare some doc including a user-space example. Should be in
the "asciidoc" format, right?

Or markdown - whatever gitlab accepts. I've granted you access to the wiki.

Thanks,
Jan
