Subject: Re: [Threads-devel] Cleanup within dll

Thank you very much for your quick and your professional answer. You are
right. I am linking statically against boost.Thread.
I want to avoid using the dll Version so I already got a workaround:
i just use the DLL_THREAD_DETACH event within the DllMain function and call
the cleanup stuff manually if the thread_specific_ptr.get() != Null
this seems to work fine. Any objections?
Is there any FAQ for boost threads what works and what not? Something like
does and don`ts? I think this would be quite usefull both for beginners and
skilled people.
