I've look at libbpf-docs.netlify.app, and it seems like it just contains a list of structs and their fields (both those that are part of libbpf API, as well as internal). Out of all functions only two are listed there (libbpf_nla_parse_nested and libbpf_nla_parse) and both are not part of libbpf API as well. So I understand that I don't see any comments due to the '/**' format (though it would be easy to run sed script adding it everywhere, just as part of an experiment), but I'm not sure why none of API functions are present there? I think kernel docs used to be hosted on readthedocs.org, seems like they are also providing hosting for open-source projects, so that would solve the problem of the hosting. Have you looked at that solution? It definitely has a bit more modern UI that Doxygen-generated one :) but I don't know what are the real differences between Sphinx and Doxygen and which one we should choose. > > In order to make this work all we would need is to format comments > above functions we want to document.
