setlocale,
localeconv
[select or query locale]
SYNOPSIS #include <locale.h> char *setlocale(int category, const char *locale); lconv *localeconv(void); char *_setlocale_r(void *reent, int category, const char *locale); lconv *_localeconv_r(void *reent);
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 “C” value for locale; strings representing other locales are not honored. (“” is also accepted; it represents the default locale for an implementation, here equivalent to “C”.) If you use NULL as the locale argument, setlocale returns a pointer to the string representing the current locale (always “C” in this implementation). The acceptable values for category are defined in locale.h as macros beginning with “LC_” although this implementation does not check the values you pass in the category argument.
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, respectively, localeconv and setlocale. The extra argument, reent, is a pointer to a reentrancy structure.
RETURNS
setlocale
returns either a pointer to a string naming the locale currently in effect
(always “C”
for this implementation), or, if the locale request cannot be honored,
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).
COMPLIANCE
ANSI C requires setlocale,
but the only locale required across all implementations is the C locale.
No supporting OS subroutines are required.
