As I said, you can "partially" check it out. At least usually the
table of contents is fully included and some sample chapters. I don't
know whether the page range you get relies on a "search" that led to
the initial page or is fixed (I felt I got parts of chapter 2 here,
not chapter 3 like you).

Regarding the book itself:

While I found the contents very useful and I am not aware of any
better book, it turned out to be rather expensive considering the fact
that it has only 400 pages and is delivered as paperback edition (here
in Germany it is sold for ~50-67 Euro, this is about ~70-94 US $).

Guido

C++ multi-platform memory-model solution, with Java orientation.
You can use all the concurrent concepts laid down by Java-memory-
model.
The idea is smooth transition from Java concurrent programming to C++
concurrent programming.

New Version: 1.4 - High Performance Hazard-Pointer:

Download: http://groups.google.com/group/cpp-framework

We tested this version a lot, so it should much more stable. (I'll be
happy to receive constructive comments, and BUG report)

New features:

1) Added "currentThread" method to Thread.
2) Added "addEndCallback" method to Thread, let you add thread
termination callbacks.
3) Added "nextLong" to Random class.
4) Better thread cleanup
5) Improved Hazard-Pointer performance, and stability. Tested with 128
threads. No memory leaks and competitive performance.
6) More examples how to use the Hazard-Pointers: "LazyList.h",
"LockFreeList.h", "LockFreeQueue.h", and "SimpleLinear.h"
7) Sorry no documentation yet.
8) In next version you can expect Linux-Intel compilation, and
documentation.

Thanks,
Moran Tzafrir.

Hi,

I am seeking for a lock free solution for strongly thread safe reference
counted pointers. Is this possible at all?

The problem is that I have to dereference the pointer and increment the
reference counter atomically. And I have absolutely no idea how to avoid
to write memory that is no longer used by the reference counter.

Any ideas?

Marcel
