DESCRIPTION
|
|
<<setlocale>> is the facility defined by ANSI C to condition the
|
|
execution environment for international collating and formatting
|
|
information; <<localeconv>> reports on the settings of the current
|
|
locale.
|
|
|
|
This is a minimal implementation, supporting only the required <<"POSIX">>
|
|
and <<"C">> values for <[locale]>; strings representing other locales are not
|
|
honored unless _MB_CAPABLE is defined.
|
|
|
|
If _MB_CAPABLE is defined, POSIX locale strings are allowed, following
|
|
the form
|
|
|
|
language[_TERRITORY][.charset][@@modifier]
|
|
|
|
<<"language">> is a two character string per ISO 639, or, if not available
|
|
for a given language, a three character string per ISO 639-3.
|
|
<<"TERRITORY">> is a country code per ISO 3166. For <<"charset">> and
|
|
<<"modifier">> see below.
|
|
|
|
Additionally to the POSIX specifier, the following extension is supported
|
|
for backward compatibility with older implementations using newlib:
|
|
<<"C-charset">>.
|
|
Instead of <<"C-">>, you can also specify <<"C.">>. Both variations allow
|
|
to specify language neutral locales while using other charsets than ASCII,
|
|
for instance <<"C.UTF-8">>, which keeps all settings as in the C locale,
|
|
but uses the UTF-8 charset.
|
|
|
|
The following charsets are recognized:
|
|
<<"UTF-8">>, <<"JIS">>, <<"EUCJP">>, <<"SJIS">>, <<"KOI8-R">>, <<"KOI8-U">>,
|
|
<<"GEORGIAN-PS">>, <<"PT154">>, <<"TIS-620">>, <<"ISO-8859-x">> with
|
|
1 <= x <= 16, or <<"CPxxx">> with xxx in [437, 720, 737, 775, 850, 852, 855,
|
|
857, 858, 862, 866, 874, 932, 1125, 1250, 1251, 1252, 1253, 1254, 1255, 1256,
|
|
1257, 1258].
|
|
|
|
Charsets are case insensitive. For instance, <<"EUCJP">> and <<"eucJP">>
|
|
are equivalent. Charset names with dashes can also be written without
|
|
dashes, as in <<"UTF8">>, <<"iso88591">> or <<"koi8r">>. <<"EUCJP">> and
|
|
<<"EUCKR">> are also recognized with dash, <<"EUC-JP">> and <<"EUC-KR">>.
|
|
|
|
Full support for all of the above charsets requires that newlib has been
|
|
build with multibyte support and support for all ISO and Windows Codepage.
|
|
Otherwise all singlebyte charsets are simply mapped to ASCII. Right now,
|
|
only newlib for Cygwin is built with full charset support by default.
|
|
Under Cygwin, this implementation additionally supports the charsets
|
|
<<"GBK">>, <<"GB2312">>, <<"eucCN">>, <<"eucKR">>, and <<"Big5">>. Cygwin
|
|
does not support <<"JIS">>.
|
|
|
|
Cygwin additionally supports locales from the file
|
|
/usr/share/locale/locale.alias.
|
|
|
|
(<<"">> is also accepted; if given, the settings are read from the
|
|
corresponding LC_* environment variables and $LANG according to POSIX rules.
|
|
|
|
This implementation also supports the modifier <<"cjknarrow">>, which
|
|
affects how the functions <<wcwidth>> and <<wcswidth>> handle characters
|
|
from the "CJK Ambiguous Width" category of characters described at
|
|
http://www.unicode.org/reports/tr11/#Ambiguous. These characters have a width
|
|
of 1 for singlebyte charsets and a width of 2 for multibyte charsets
|
|
other than UTF-8. For UTF-8, their width depends on the language specifier:
|
|
it is 2 for <<"zh">> (Chinese), <<"ja">> (Japanese), and <<"ko">> (Korean),
|
|
and 1 for everything else. Specifying <<"cjknarrow">> forces a width of 1,
|
|
independent of charset and language.
|
|
|
|
If you use <<NULL>> as the <[locale]> argument, <<setlocale>> returns a
|
|
pointer to the string representing the current locale. The acceptable
|
|
values for <[category]> are defined in `<<locale.h>>' as macros
|
|
beginning with <<"LC_">>.
|
|
|
|
<<localeconv>> returns a pointer to a structure (also defined in
|
|
`<<locale.h>>') describing the locale-specific conventions currently
|
|
in effect.
|
|
|
|
<<_localeconv_r>> and <<_setlocale_r>> are reentrant versions of
|
|
<<localeconv>> and <<setlocale>> respectively. The extra argument
|
|
<[reent]> is a pointer to a reentrancy structure.
|
|
|
|
RETURNS
|
|
A successful call to <<setlocale>> returns a pointer to a string
|
|
associated with the specified category for the new locale. The string
|
|
returned by <<setlocale>> is such that a subsequent call using that
|
|
string will restore that category (or all categories in case of LC_ALL),
|
|
to that state. The application shall not modify the string returned
|
|
which may be overwritten by a subsequent call to <<setlocale>>.
|
|
On error, <<setlocale>> returns <<NULL>>.
|
|
|
|
<<localeconv>> returns a pointer to a structure of type <<lconv>>,
|
|
which describes the formatting and collating conventions in effect (in
|
|
this implementation, always those of the C locale).
|
|
|
|
PORTABILITY
|
|
ANSI C requires <<setlocale>>, but the only locale required across all
|
|
implementations is the C locale.
|
|
|
|
NOTES
|
|
There is no ISO-8859-12 codepage. It's also refused by this implementation.
|
|
|
|
No supporting OS subroutines are required.
