[Xenomai] xenomai API

[Xenomai] xenomai API

[Giampaolo Bellini]

Hi all

  I'm totally new to xenomai... so my question could be stupid :-(

  I wonder if there are xenomai's counterpart of RTAI's SCB (Shared memory
Circular Buffer),  MBX (MailBox) and LXRT (soft-hard real time in user space
).

        thanks a lot

                    Giampaolo

Hi,

I do not know enough RTAI APIs to answer this question. Anyway, from the
sound of it, something equivalent would be shared memory, and message
queues, which both the native and posix skins propose.
You may find some answers, starting from here:
http://www.xenomai.org/documentation/xenomai-2.6/html/api/group__posix.html

You will also find some documentation on xenomai website:

Yes, xenomai has always proposed hard real-time in user-space. And in
fact, writing hard real-time applications in kernel-space is considered
deprecated.

RT_QUEUE for the shared memory property.

   MBX (MailBox)

RT_BUFFER.

As pointed out by Gilles already, this is built in.
