[Xenomai] V3 heap usage

[Xenomai] V3 heap usage

[Stéphane ANCELOT]

Hi,

Since rtheap compat alchemy seems broken, I wanted to try native heap 
dynamic allocation.

I found xnheap_ functions.

However, in this case, I have to manage heap byte alignment.

These are the right functions to use ? or I missed something ???

Regards,
S.Ancelot

Your test code is broken, not the API so far. Besides, I can only repeat
myself: there is no rtheap compat wrappers in the transition kit, simply
because there is no need for it:

These are kernel-space inner services for implementing the dual kernel
system. You most likely don't want to use them.

No, that would make no sense, you must have misread the internal docs or
code.

You seem to be missing the documentation:
