Does ASIO really still uses reactor instead of proactor on some OSes or is documentation just outdated?
If you go to https://www.boost.org/doc/libs/1_80_0/doc/html/boost_asio/overview/core/asyn... you will see that it says: * On many platforms, Boost.Asio implements the Proactor design pattern in terms of a Reactor, such as select, epoll or kqueue. This implementation approach corresponds to the Proactor design pattern as follows: * *[...]* * On Windows NT, 2000 and XP, Boost.Asio takes advantage of overlapped I/O to provide an efficient implementation of the Proactor design pattern. This implementation approach corresponds to the Proactor design pattern as follows: * I am unfortunately not a pattern or OS expert, but I would expect that on every modern OS proactor can be implemented without using reactor, e.g. see *https://stackoverflow.com/a/57451551/700825 <https://stackoverflow.com/a/57451551/700825>* The fact that mentioned Windows are NT, XP and 2000 also furthers my suspicion that docs are outdated.
Yes, asio supports io_uring. Since approx. Boost 1.78 or thereabouts. On Sat, 29 Oct 2022 at 14:54, Ivan Matek via Boost <boost@lists.boost.org> wrote:

Thank you. Would be nice if docs were updated. I know Boost is just volunteers and that I can just write a pull request, but as I said IDK enough about ASIO/OSes to write it so if I do it poor reviewer will have to rewrite it anyway. :)
regards, Ivan

Any update/pull request has to happen in the standalone repo: <https://github.com/chriskohlhoff/asio> Thanks

Thanks
Thank you for the pointer :) , I made an issue, I know it is not a big deal, but it is the first result for me when googling: boost asio proactor
