A simple set of io-uring bindings in Haskell

io-uring

A simple set of io-uring bindings in Haskell. See Main.hs for an example on how to use it. The example code can be run with cabal run.

Requirements

Since the io_uring interface was only added to the Linux kernel in version 5.1 (released around May 2019) so it's possible that you are running a kernel version that supports it. From the command line, uname -r will tell you the kernel version of your system.

Warning

It is NOT advised to cabal install --lib this repo to get the libraries installed as non-hidden modules. Part of the bindings include C-- code that prevents the GHCi bytecode interpreter from even starting up.

io-uring's Issues

Clean way to free Uring

Maybe I misunderstand how it works, but there does not seem to be a clean way to close the Uring from Haskell land. There is the uringFptr in the URing data structure that is a ForeignPtr HsURing coming from c_free_uring but I don't really understand how to use it.
