errno [-ls] [--list]

errno [-s] [--search] {word}

errno [-S] [--search-all-locales] {word}

errno looks up errno macro names, errno codes, and the corresponding descriptions. For example, if given ENOENT on a Linux system, it prints out the code 2 and the description "No such file or directory". If given the code 2, it prints ENOENT and the same description.
