From fd1b5c0fb6ca63dd76e833672be840cc4c3a7eff Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sun, 9 Apr 2000 17:43:29 +0000 Subject: Update. 2000-04-09 Ulrich Drepper Implement handling of restartable conversion functions according to ISO C. * iconv/gconv.h (__gconv_fct): Add additional parameter. * iconv/gconv_int.h (__BUILTIN_TRANS): Likewise. * iconv/gconv.c: Pass additional parameter to conversion function. * iconv/gconv_simple.c (internal_ucs4_loop_single): New function. (internal_ucs4le_loop_single): New function. (__gconv_transform_ascii_internal): Define ONE_DIRECTION. (__gconv_transform_internal_ascii): Likewise. (__gconv_transform_internal_utf8): Likewise. (__gconv_transform_utf8_internal): Likewise. (__gconv_transform_ucs2_internal): Likewise. (__gconv_transform_internal_ucs2): Likewise. (__gconv_transform_ucs2reverse_internal): Likewise. (__gconv_transform_internal_ucs2reverse): Likewise. (internal_ucs4le_loop_unaligned): Before return __GCONV_INCOMPLETE_INPUT check that the remaining bytes really form a valid character. Otherwise return __GCONV_ILLEGAL_INPUT. (__gconv_transform_utf8_internal): Define STORE_REST and UNPACK_BYTES. * iconv/loop.c: Fit in definition of function to convert one character for processing of left-over bytes from the state object. * iconv/skeleton.c (gconv): Rename inbuf to inptrp and inbufend to inend to match names in loop functions. (RESET_INPUT_BUFFER): Change apprpriately. (gconv): If needed, call function to process bytes from the state object. Similar at the end: store left over bytes if input is incomplete. Take extra argument and add new argument to all calls of the conversion function. * iconvdata/iso-2022-cn.c: Adjust numeric values used to store information in the state object to not conflict with length count. * iconvdata/iso-2022-jp.c: Likewise. * iconvdata/iso-2022-kr.c: Likewise. * iconvdata/unicode.c: Adjust for change change in parameters of skeleton function. * iconvdata/utf-16.c: Likewise. * libio/iofwide.c: Add new parameter to all calls of conversion function. * 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. * iconvdata/gbgbk.c: Always define MAX_NEEDED_OUTPUT and MAX_NEEDED_INPUT. --- iconvdata/iso-2022-jp.c | 46 +++++++++++++++++++++++++++------------------- 1 file changed, 27 insertions(+), 19 deletions(-) (limited to 'iconvdata/iso-2022-jp.c') diff --git a/iconvdata/iso-2022-jp.c b/iconvdata/iso-2022-jp.c index 99f45dad7e..105fd4753b 100644 --- a/iconvdata/iso-2022-jp.c +++ b/iconvdata/iso-2022-jp.c @@ -89,13 +89,14 @@ struct iso2022jp_data enum { ASCII_set = 0, - JISX0208_1978_set, - JISX0208_1983_set, - JISX0201_Roman_set, - JISX0201_Kana_set, - GB2312_set, - KSC5601_set, - JISX0212_set + JISX0208_1978_set = 8, + JISX0208_1983_set = 16, + JISX0201_Roman_set = 24, + JISX0201_Kana_set = 32, + GB2312_set = 40, + KSC5601_set = 48, + JISX0212_set = 56, + CURRENT_SEL_MASK = 56 }; /* The second value stored is the designation of the G2 set.
