Hello
That may not be needed , Since the numbers here are much smaller and more
importantly positive. And Hence the help of such a generic library is not be
needed. Besides i have most of the code ready, i just have to port it into
boost specific format. So I am  looking for the community's interest in the
proposal.
Thank you

I think it is the right interface.  any_cast is, of course,
highly specific.

Submit a patch via Trac and mention the Trac ticket here.  If the
maintainer (Kevlin Henney) doesn't notice the ticket after a reasonable
time, we can try other ways to get his attention.

Message-ID:

Hello all,
I am working on a library like DotNet FileSystemWatcher (
http://msdn.microsoft.com/en-us/library/system.io.filesystemwatcher%28VS.80%...
)
Basically the library monitors for file system changes and notifies
throwing
events.
First, it will support the following platforms:
   - Windows NT 5.0 (Windows 2000) or higher using O/I Completion Port.
   - Linux 2.6.13 or higher using inotify.
   - FreeBSD 4.1 or higher using kqueue.
   - NetBSD 2.0 or higher using kqueue.
 - OpenBSD 3.6 higher using kqueue.    (Not sure which version supports it)
   - MacOS/X 10.4 higher using kqueue. (Not sure which version supports it)
Future supported platforms:
   - Linux from 2.4.0-test9 2.6.12 using dnotify.
   - Sun OpenSolaris using FEM API.
Testing:
   I am testing the library on FreeBSD 7.2, Linux 2.6.31, Windows XP
(Windows NT 5.1).
   I need help to test on older versions of these operating systems.
   Also in NetBSD, OpenBSD and mainly on MacOSX because I do not have the
necessary hardware.
I would like to include this library in Boost, I think would be useful.
What do you think? If so, I would like to have a mentor (like GSoC) and
experienced in Boost development.
Thanks and regards,
Fernando Pelliccioni

My humble opinion to the matter:
I think it is a great idea to try and make Castor part of Boost. I have
been using Castor in my research for a while now, and I think that it is
definitely Boost-material. A logic engine can be a powerful tool, and it is
a shame that C++ doesn't have one readily available. I am confident that
Castor is the best choice for adding logic support to Boost.
As far as I know, Boost is the most popular code-base that is not part of
the C++ standard library yet. So, making Castor part of Boost would be a
great way of increasing Castor's visibility. It would be nice to keep Castor
available as a stand-alone library, so that you don't need Boost if you only
want to use Castor. But I am sure that this issue can be solved: Castor
could be a Boost "companion" library, or one could have a stand-alone
version and a Boost version side-by-side. Although this last solution
doesn't seem that great to me.
I hope I will find the time to do some testing for Castor 1.1. Keep in
touch!

Just for the question to be complete, that's my Something class:
class Something
{
       private:
               int val;
       public:
               Something(){};
               Something(int i):val(i){};
               void set_val(int i)     {val=i;};
               int get_val()           {return val;};
};
But that 'int' is just a placeholder. This class is intended to be a
bit more complex...
best regards

Hi Janek,
I'd like to know what's your goal when you declare a vector of "atomic"
variables. What is the result you are looking for?

Hi, just to understand better your concern.
What kind of problems do you expect to have?
have you already tried it?
What do you expect from the atomic library?
Best,
