There is no POSIX function to extract TODIGIT info, so it is useless for now. todigit() is SCO extension and its manpage says: The macro todigit returns the digit character corresponding to its integer argument. The argument must be in the range 0-9, otherwise the behavior is undefined. iswdigit() have the same 0-9 restriction as isdigit() just accepts wint_t -- http://ache.pp.ru/ _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-i18n To unsubscribe, send any mail to "[email protected]"
