From 6990326c21e6d767e3531a00782af1e091eab4fe Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Wed, 19 Jun 1996 05:38:55 +0000 Subject: Wed Jun 19 01:27:57 1996 Roland McGrath * math/Makefile (distribute): Add ieee-math.c. Wed Jun 19 03:24:58 1996 Ulrich Drepper * locale/codeset_name.c: New file. Provide function for information about currently used character set. * locale/Makefile (routines): Add codeset_name. * locale/langinfo.h (_NL_CTYPE_CODESET_NAME): Add new constant. * locale/localeinfo.h: Change magic number because of incompatible change. * locale/C-ctype.c: Add initializer for new field `codeset_name'. * locale/programs/ld-ctype.c: Implement handling of `codeset_name'. * locale/programs/locfile.c: Don't depend in pre-2.0 Linux specific name `MAX_IOVEC'. Instead use standard name `UIO_MAXIOV'. * locale/setlocale.c (setlocale): Initialize local variables to prevent warnings. --- locale/C-ctype.c | 3 ++- locale/Makefile | 2 +- locale/codeset_name.c | 31 +++++++++++++++++++++++++++++++ locale/langinfo.h | 1 + locale/localeinfo.h | 2 +- locale/programs/ld-ctype.c | 9 +++++++++ locale/programs/locfile.c | 6 +----- locale/setlocale.c | 4 ++-- 8 files changed, 48 insertions(+), 10 deletions(-) create mode 100644 locale/codeset_name.c (limited to 'locale') diff --git a/locale/C-ctype.c b/locale/C-ctype.c index 0eb131c050..0cbae19836 100644 --- a/locale/C-ctype.c +++ b/locale/C-ctype.c @@ -920,6 +920,7 @@ const struct locale_data _nl_C_LC_CTYPE = "print\0" "graph\0" "blank\0" "cntrl\0" "punct\0" "alnum\0" }, { string: "tolower\0" "toupper\0" }, { string: _nl_C_LC_CTYPE_width }, - { word: 2 } + { word: 2 }, + { string: "ISO_646.IRV:1983" } } }; diff --git a/locale/Makefile b/locale/Makefile index 2ee2650f5b..8069e7e311 100644 --- a/locale/Makefile +++ b/locale/Makefile @@ -29,7 +29,7 @@ distribute = localeinfo.h categories.def \ locfile-kw.gperf locfile-kw.h linereader.h \ locales.h locfile.h stringtrans.h weight.h charset.h routines = setlocale findlocale loadlocale localeconv nl_langinfo \ - mb_cur_max + mb_cur_max codeset_name categories = ctype messages monetary numeric time collate aux = $(categories:%=lc-%) $(categories:%=C-%) SYS_libc C_name others = localedef locale diff --git a/locale/codeset_name.c b/locale/codeset_name.c new file mode 100644 index 0000000000..c7fd818e70 --- /dev/null +++ b/locale/codeset_name.c @@ -0,0 +1,31 @@ +/* Internal function to return the name of the current codeset. +Copyright (C) 1996 Free Software Foundation, Inc. +This file is part of the GNU C Library. +Contributed by Ulrich Drepper , 1996. + +The GNU C Library is free software; you can redistribute it and/or +modify it under the terms of the GNU Library General Public License as +published by the Free Software Foundation; either version 2 of the +License, or (at your option) any later version. + +The GNU C Library is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
