Thanks, Alan! That looks very promising. I could not make it work, though, and I guess that is because I use linux and do not know what to change for what. I installed libcerf but I assume something else is missing. In any case, this is one of the things it would be nice to have, at least as a module. I have no idea on how to realize that, though.

You likely also need to install libffi - I do not know what package this is on your flavor of linux - Luigi is the ffi specialist!

FFI is integrated in LuaTeX >= 1.03 In you example you load libcerf but you are not using it. What you are actually using are the Bessel function from the C Standard library. GCC includes them as a GNU extension. https://www.gnu.org/software/libc/manual/html_node/Special-Functions.html#in... Your example also works if you remove libcerf (at least for me on Linux).
