The trouble with I/O multiplexing in a language like C is that the callbacks and state machines get quite complex as you need more functionality. In C++ you can at least do closures, so it's easier to manage. I recently wanted to add networking to my Zig project and decided to do some yak shaving and implemented a fiber runtime with async I/O to avoid the callback complexity. https://github.com/lalinsky/zio
In C++20 you can use asio + coroutines. I find it pretty nice to work with.
Wow nice! How does this compare to libxev?
I was curious as well and looks like this abstracts over libxev: https://github.com/lalinsky/zio/blob/main/build.zig#L7
Indeed, it's a translation of the callback-based libxev events to coroutines. I ended up temporarily forking libxev, to add support for vectored I/O and other small fixes, but all those changes will be upstreamed.

As usual, no FreeBSD support.
