For the work on Linux extended file attributes support I needed few standard error codes. I looked them up manually but I was curious if it were possible to do it automatically. I have come up with what is committed in repository https://github.com/wilx/parse-linux-libc-error-codes. I am just offering it as a POC of something that might be useful to JNA project to generate a list of error codes.
