struct atomic_cas64 { .... #elif defined(_M_IX86) return InterlockedCompareExchange(reinterpret_cast(addr), reinterpret_cast<LONG>(nw), // reinterpret_cast: cannot cast boost::int64_t to LONG reinterpret_cast<LONG>(old)) == old; // reinterpret_cast: cannot cast boost::int64_t to LONG

thanks, i will have a look at the code ... i am neither using windows, nor msvc, so the win32-specific code is not very well tested ...

More questions: what is the status of LockFree?

i consider the implementation as quite stable and the library is submitted for review (though i didn't get any reply on the review request :/)

Are there any alternatives for atomic_int?

there is a boost::detail::atomic_count ... tim -- tim@klingt.org http://tim.klingt.org /"\ ASCII Ribbon Campaign \ / no HTML in email & vCards X no proprietary attachments / \ use open standards
