2000-06-15 Ulrich Drepper <drepper@redhat.com> * iconv/gconv.h (__gconv_fct): Change type of fifth parameter to unsigned char **. (__gconv_init_fct): Remove two parameters. * iconv/gconv_int.h (__gconv_transliterate): Renamed from gconv_transliterate. Remove two parameters. Change prototypes of builtin functions according to __gconv_fct change. * iconv/skeleton.c: Change type of fifth parameter. make sure it is != NULL only during error handling. Stop in this case after the conversion. * iconv/gconv_trans.c: Replace with real implementation for __gconv_transliterate. * iconv/gconv_open.c: Adjust for renaming of __gconv_transliterate. * iconv/gconv.c: Change calls to downstream functions once again. Use NULL for the fifth parameter instead of pointer to output buffer. * libio/iofwide.c: Likewise. * wcsmbs/btowc.c: Likewise. * wcsmbs/mbrtowc.c: Likewise. * wcsmbs/mbsnrtowcs.c: Likewise. * wcsmbs/mbsrtowcs.c: Likewise. * wcsmbs/wcrtomb.c: Likewise. * wcsmbs/wcsnrtombs.c: Likewise. * wcsmbs/wcsrtombs.c: Likewise. * wcsmbs/wctob.c: Likewise. * iconv/gconv_simple.c: Remove two parameters from error handling function call. * iconvdata/8bit-gap.c: Likewise. * iconvdata/8bit-generic.c: Likewise. * iconvdata/ansi_x3.110.c: Likewise. * iconvdata/big5.c: Likewise. * iconvdata/big5hkscs.c: Likewise. * iconvdata/euc-cn.c: Likewise. * iconvdata/euc-jp.c: Likewise. * iconvdata/euc-kr.c: Likewise. * iconvdata/euc-tw.c: Likewise. * iconvdata/gbgbk.c: Likewise. * iconvdata/gbk.c: Likewise. * iconvdata/iso-2022-cn.c: Likewise. * iconvdata/iso-2022-jp.c: Likewise. * iconvdata/iso-2022-kr.c: Likewise. * iconvdata/iso646.c: Likewise. * iconvdata/iso8859-1.c: Likewise. * iconvdata/iso_6937-2.c: Likewise. * iconvdata/iso_6937.c: Likewise. * iconvdata/johab.c: Likewise. * iconvdata/sjis.c: Likewise. * iconvdata/t.61.c: Likewise. * iconvdata/uhc.c: Likewise. * iconvdata/unicode.c: Likewise. * iconvdata/utf-16.c: Likewise.
