sl@0: * FUNCTION
sl@0: * <<setlocale>>, <<localeconv>>---select or query locale
sl@0: * INDEX
sl@0: * setlocale
sl@0: * INDEX
sl@0: * localeconv
sl@0: * INDEX
sl@0: * _setlocale_r
sl@0: * INDEX
sl@0: * _localeconv_r
sl@0: * ANSI_SYNOPSIS
sl@0: * #include <locale.h>
sl@0: * char *setlocale(int <[category]>, const char *<[locale]>);
sl@0: * lconv *localeconv(void);
sl@0: * char *_setlocale_r(void *<[reent]>,
sl@0: * int <[category]>, const char *<[locale]>);
sl@0: * lconv *_localeconv_r(void *<[reent]>);
sl@0: * TRAD_SYNOPSIS
sl@0: * #include <locale.h>
sl@0: * char *setlocale(<[category]>, <[locale]>)
sl@0: * int <[category]>;
sl@0: * char *<[locale]>;
sl@0: * lconv *localeconv();
sl@0: * char *_setlocale_r(<[reent]>, <[category]>, <[locale]>)
sl@0: * char *<[reent]>;
sl@0: * int <[category]>;
sl@0: * char *<[locale]>;
sl@0: * lconv *_localeconv_r(<[reent]>);
sl@0: * char *<[reent]>;
sl@0: * <<setlocale>> is the facility defined by ANSI C to condition the
sl@0: * execution environment for international collating and formatting
sl@0: * information; <<localeconv>> reports on the settings of the current
sl@0: * locale.
sl@0: * This is a minimal implementation, supporting only the required <<``C''>>
sl@0: * value for <[locale]>; strings representing other locales are not
sl@0: * honored.  (<<``''>> is also accepted; it represents the default locale
sl@0: * for an implementation, here equivalent to <<``C''>>.)
sl@0: * If you use <<NULL>> as the <[locale]> argument, <<setlocale>> returns
sl@0: * a pointer to the string representing the current locale (always
sl@0: * <<``C''>> in this implementation).  The acceptable values for
sl@0: * <[category]> are defined in `<<locale.h>>' as macros beginning with
sl@0: * <<"LC_">>, but this implementation does not check the values you pass
sl@0: * in the <[category]> argument.
sl@0: * <<localeconv>> returns a pointer to a structure (also defined in
sl@0: * `<<locale.h>>') describing the locale-specific conventions currently
sl@0: * in effect.  
sl@0: * <<_localeconv_r>> and <<_setlocale_r>> are reentrant versions of
sl@0: * <<localeconv>> and <<setlocale>> respectively.  The extra argument
sl@0: * <[reent]> is a pointer to a reentrancy structure.
sl@0: * RETURNS
sl@0: * <<setlocale>> returns either a pointer to a string naming the locale
sl@0: * currently in effect (always <<``C''>> for this implementation), or, if
sl@0: * the locale request cannot be honored, <<NULL>>.
sl@0: * <<localeconv>> returns a pointer to a structure of type <<lconv>>,
sl@0: * which describes the formatting and collating conventions in effect (in
sl@0: * this implementation, always those of the C locale).
sl@0: * PORTABILITY
sl@0: * ANSI C requires <<setlocale>>, but the only locale required across all
sl@0: * implementations is the C locale.
sl@0: * No supporting OS subroutines are required.
sl@0: * setlocale, localeconv : internationalize your locale.
sl@0: * (Only "C" or null supported).
