Description

Bindings to the Linux io_uring kernel IO interfaces. See https://github.com/ocaml-multicore/eio for a higher-level API using this.

README

ocaml-uring -- bindings to Linux io_uring

These are OCaml bindings for the Linux io_uring stack (an alternative to using syscalls such as select or epoll).

The Eio library provides a higher-level effects-based API that uses this library to implement its Linux backend, but ocaml-uring may be useful with single-core non-effects versions of OCaml too.

To use the library directly:

  1. Call Uring.create to initialise a ring.

  2. Add IO requests to the ring using functions such as Uring.readv.

  3. Call Uring.submit to notify the kernel of the new requests.

  4. Call Uring.wait to wait until an operation is complete.

The tests directory contains some examples.
