I know this message is ancient, but if you are still looking for atomic
primitives I just ran across some in the boost code base. I can't figure
out how to use them (!) but perhaps you can? Boost, if you don't know,
seems to be kind of a proving ground for the C++ working group. Lots of
libraries which are cross platform and written by smart people. See
www.boost.org.
Hope this helps... mo
PS At least the code might provide some hints for how to implement
atomic primitives yourself. The code is open, but not GPLd.

Don't use these, if glibc supports your architecture.
But, I prefer to avoid using kernel header
files in application
code, mostly for portability and maintenance reasons.
Distributions handle them in non-standard ways, making it hard
to explain to users how to resolve the dependency. Also,
porting to non-Linux platforms becomes problematic.
And as there might be privilegded operations involved, these
headers are a big no-no.

AFAICT, these are for the library's own use, not part of the
supported external interface. I'll investigate further.
These I use myself and I can recommend them, as long as you use
GCC or a compatible compiler. They are mad for user space and
survive even preemption quite well.
