FUNCTION
<<setlocale>>, <<localeconv>>---select or query locale
INDEX
setlocale
INDEX
localeconv
INDEX
_setlocale_r
INDEX
_localeconv_r
ANSI_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]>);
TRAD_SYNOPSIS
#include <locale.h>
char *setlocale(<[category]>, <[locale]>)
int <[category]>;
char *<[locale]>;
lconv *localeconv();
char *_setlocale_r(<[reent]>, <[category]>, <[locale]>)
char *<[reent]>;
int <[category]>;
char *<[locale]>;
lconv *_localeconv_r(<[reent]>);
char *<[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 unless MB_CAPABLE is defined in which case three new
extensions are allowed for LC_CTYPE only: <<''C-JIS''>>, <<''C-EUCJP''>>,
and <<''C-SJIS''>>. (<<``''>> 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_">>, but 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
<<localeconv>> and <<setlocale>> respectively. 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).
PORTABILITY
ANSI C requires <<setlocale>>, but the only locale required across all
implementations is the C locale.
No supporting OS subroutines are required.
