---|
| 23 | DESCRIPTION |
---|
| 24 | <<setlocale>> is the facility defined by ANSI C to condition the |
---|
| 25 | execution environment for international collating and formatting |
---|
| 26 | information; <<localeconv>> reports on the settings of the current |
---|
| 27 | locale. |
---|
| 28 | |
---|
| 29 | This is a minimal implementation, supporting only the required <<"POSIX">> |
---|
| 30 | and <<"C">> values for <[locale]>; strings representing other locales are not |
---|
| 31 | honored unless _MB_CAPABLE is defined. |
---|
| 32 | |
---|
| 33 | If _MB_CAPABLE is defined, POSIX locale strings are allowed, following |
---|
| 34 | the form |
---|
| 35 | |
---|
| 36 | language[_TERRITORY][.charset][@@modifier] |
---|
| 37 | |
---|
| 38 | <<"language">> is a two character string per ISO 639, or, if not available |
---|
| 39 | for a given language, a three character string per ISO 639-3. |
---|
| 40 | <<"TERRITORY">> is a country code per ISO 3166. For <<"charset">> and |
---|
| 41 | <<"modifier">> see below. |
---|
| 42 | |
---|
| 43 | Additionally to the POSIX specifier, the following extension is supported |
---|
| 44 | for backward compatibility with older implementations using newlib: |
---|
| 45 | <<"C-charset">>. |
---|
| 46 | Instead of <<"C-">>, you can also specify <<"C.">>. Both variations allow |
---|
| 47 | to specify language neutral locales while using other charsets than ASCII, |
---|
| 48 | for instance <<"C.UTF-8">>, which keeps all settings as in the C locale, |
---|
| 49 | but uses the UTF-8 charset. |
---|
| 50 | |
---|
| 51 | The following charsets are recognized: |
---|
| 52 | <<"UTF-8">>, <<"JIS">>, <<"EUCJP">>, <<"SJIS">>, <<"KOI8-R">>, <<"KOI8-U">>, |
---|
| 53 | <<"GEORGIAN-PS">>, <<"PT154">>, <<"TIS-620">>, <<"ISO-8859-x">> with |
---|
| 54 | 1 <= x <= 16, or <<"CPxxx">> with xxx in [437, 720, 737, 775, 850, 852, 855, |
---|
| 55 | 857, 858, 862, 866, 874, 932, 1125, 1250, 1251, 1252, 1253, 1254, 1255, 1256, |
---|
| 56 | 1257, 1258]. |
---|
| 57 | |
---|
| 58 | Charsets are case insensitive. For instance, <<"EUCJP">> and <<"eucJP">> |
---|
| 59 | are equivalent. Charset names with dashes can also be written without |
---|
| 60 | dashes, as in <<"UTF8">>, <<"iso88591">> or <<"koi8r">>. <<"EUCJP">> and |
---|
| 61 | <<"EUCKR">> are also recognized with dash, <<"EUC-JP">> and <<"EUC-KR">>. |
---|
| 62 | |
---|
| 63 | Full support for all of the above charsets requires that newlib has been |
---|
| 64 | build with multibyte support and support for all ISO and Windows Codepage. |
---|
| 65 | Otherwise all singlebyte charsets are simply mapped to ASCII. Right now, |
---|
| 66 | only newlib for Cygwin is built with full charset support by default. |
---|
| 67 | Under Cygwin, this implementation additionally supports the charsets |
---|
| 68 | <<"GBK">>, <<"GB2312">>, <<"eucCN">>, <<"eucKR">>, and <<"Big5">>. Cygwin |
---|
| 69 | does not support <<"JIS">>. |
---|
| 70 | |
---|
| 71 | Cygwin additionally supports locales from the file |
---|
| 72 | /usr/share/locale/locale.alias. |
---|
| 73 | |
---|
| 74 | (<<"">> is also accepted; if given, the settings are read from the |
---|
| 75 | corresponding LC_* environment variables and $LANG according to POSIX rules.) |
---|
| 76 | |
---|
| 77 | This implementation also supports the modifier <<"cjknarrow">>, which |
---|
| 78 | affects how the functions <<wcwidth>> and <<wcswidth>> handle characters |
---|
| 79 | from the "CJK Ambiguous Width" category of characters described at |
---|
| 80 | http://www.unicode.org/reports/tr11/#Ambiguous. These characters have a width |
---|
| 81 | of 1 for singlebyte charsets and a width of 2 for multibyte charsets |
---|
| 82 | other than UTF-8. For UTF-8, their width depends on the language specifier: |
---|
| 83 | it is 2 for <<"zh">> (Chinese), <<"ja">> (Japanese), and <<"ko">> (Korean), |
---|
| 84 | and 1 for everything else. Specifying <<"cjknarrow">> forces a width of 1, |
---|
| 85 | independent of charset and language. |
---|
| 86 | |
---|
| 87 | If you use <<NULL>> as the <[locale]> argument, <<setlocale>> returns a |
---|
| 88 | pointer to the string representing the current locale. The acceptable |
---|
| 89 | values for <[category]> are defined in `<<locale.h>>' as macros |
---|
| 90 | beginning with <<"LC_">>. |
---|
| 91 | |
---|
| 92 | <<localeconv>> returns a pointer to a structure (also defined in |
---|
| 93 | `<<locale.h>>') describing the locale-specific conventions currently |
---|
| 94 | in effect. |
---|
| 95 | |
---|
| 96 | <<_localeconv_r>> and <<_setlocale_r>> are reentrant versions of |
---|
| 97 | <<localeconv>> and <<setlocale>> respectively. The extra argument |
---|
| 98 | <[reent]> is a pointer to a reentrancy structure. |
---|
| 99 | |
---|
| 100 | RETURNS |
---|
| 101 | A successful call to <<setlocale>> returns a pointer to a string |
---|
| 102 | associated with the specified category for the new locale. The string |
---|
| 103 | returned by <<setlocale>> is such that a subsequent call using that |
---|
| 104 | string will restore that category (or all categories in case of LC_ALL), |
---|
| 105 | to that state. The application shall not modify the string returned |
---|
| 106 | which may be overwritten by a subsequent call to <<setlocale>>. |
---|
| 107 | On error, <<setlocale>> returns <<NULL>>. |
---|
| 108 | |
---|
| 109 | <<localeconv>> returns a pointer to a structure of type <<lconv>>, |
---|
| 110 | which describes the formatting and collating conventions in effect (in |
---|
| 111 | this implementation, always those of the C locale). |
---|
| 112 | |
---|
| 113 | PORTABILITY |
---|
| 114 | ANSI C requires <<setlocale>>, but the only locale required across all |
---|
| 115 | implementations is the C locale. |
---|
| 116 | |
---|
| 117 | NOTES |
---|
| 118 | There is no ISO-8859-12 codepage. It's also refused by this implementation. |
---|
| 119 | |
---|
| 120 | No supporting OS subroutines are required. |
