My suggestion is: "The function iswblank() is thread safe with exceptions (locale). See "Safety Concepts" for more information." Then describe the locale issue once in the "Safety Concepts" section. This reduces duplicated text and simplifies each man page. Users that know what "locale" means can scroll quickly, users that don't can look it up and learn. Does that make sense? My further suggestion is to use the same ~20 exception notes as glibc e.g. race, const, locale, env, hostid, sigintr, init, lock, corrupt, heap, dlopen, plugin, i18ln, fd, mem, sig, term, and cwd (we also have !posix to indicate it is known not to conform with posix). The glibc manual is marked with them now, you can see iswblank here: http://www.gnu.org/software/libc/manual/html_mono/libc.html#index-iswblank-486 Cheers, Carlos. -- To unsubscribe from this list: send the line "unsubscribe linux-man" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
