The idea seems good. I have not tested it, though. It seems better to implement c16rtomb_l() and mbrtoc16_l() in the same way, rather than duplicating the UTF-16 coding and passing a pointer to a mbstate_t which actually has only 120 bytes of storage rather than the required 128 bytes. > Now we still have the case where the system is built WITHOUT_ICONV=.

If ache@ is right about configure scripts, it is an option to expose the new functions only for WITH_ICONV=. -- Jilles Tjoelker _______________________________________________ svn-src-all@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
