I’d like to wrap a C library for use within Eio code. That library opens a network connection on its own, but I’m able to fetch the file descriptor of the open socket. It even operates in non-blocking mode. But how do I… --- ## [Eio Unix.EADDRNOTAVAIL on socket bind!?](https://discuss.ocaml.org/t/eio-unix-eaddrnotavail-on-socket-bind/15809)

Hello all! I was having some issues when making use of the Eio library, specifically when attempting to create a UDP socket and sending data. As a proof of concept, I went ahead and wrote out the Unix code by hand to try… --- ## [Bounds checks for String and Bytes when retrieving (or setting) subparts thereof](https://discuss.ocaml.org/t/bounds-checks-for-string-and-bytes-when-retrieving-or-setting-subparts-thereof/14422)

Dear all, I sometimes have binary data that I need to decode. Code is normally roughly: let guard p e = if p then Ok () else Error e let ( let\* ) = Result.bind let decode\_header str = let\* () = guard (String.length… --- ## [Dns and hosts file](https://discuss.ocaml.org/t/dns-and-hosts-file/10649)

We have the Dns module which is great, but just implements the network layer. Is there a suggested solution for how to implement full DNS lookups that use the hosts file? --- ## [Using AF\_XDP sockets for high-performance packet processing in OCaml](https://discuss.ocaml.org/t/using-af-xdp-sockets-for-high-performance-packet-processing-in-ocaml/6106)
