NAME
       I18N::Langinfo - query locale information

SYNOPSIS
         use I18N::Langinfo;

DESCRIPTION
       The langinfo() function queries various locale information that can be
       used to localize output and user interfaces.  The langinfo() requires
       one numeric argument that identifies the locale constant to query: if
       no argument is supplied, $ is used.  The numeric constants appropriate
       to be used as arguments are exportable from I18N::Langinfo.

       The following example will import the langinfo() function itself and
       three constants to be used as arguments to langinfo(): a constant for
       the abbreviated first day of the week (the numbering starts from Sunday
       = 1) and two more constants for the affirmative and negative answers
       for a yes/no question in the current locale.

           use I18N::Langinfo qw(langinfo ABDAY1 YESSTR NOSTR);

           my ($abday1, $yesstr, $nostr) = map { langinfo } qw(ABDAY1 YESSTR NOSTR);

           print "$abday1? [$yesstr/$nostr] ";

       In other words, in the "C" (or English) locale the above will probably
       print something like:

           Sun? [yes/no]

       but under a French locale

           dim? [oui/non]

       The usually available constants are

           ABDAY1 ABDAY2 ABDAY3 ABDAY4 ABDAY5 ABDAY6 ABDAY7
           ABMON1 ABMON2 ABMON3 ABMON4 ABMON5 ABMON6
           ABMON7 ABMON8 ABMON9 ABMON10 ABMON11 ABMON12
           DAY1 DAY2 DAY3 DAY4 DAY5 DAY6 DAY7
           MON1 MON2 MON3 MON4 MON5 MON6
           MON7 MON8 MON9 MON10 MON11 MON12

       for abbreviated and full length days of the week and months of the
       year,

           DTFMT DFMT TFMT

       for the date-time, date, and time formats used by the strftime() func-
       tion (see POSIX)

           AMSTR PMSTR TFMTAMPM

       for the locales for which it makes sense to have ante meridiem and post
       meridiem time formats,

           CODESET CRNCYSTR RADIXCHAR

       for the character code set being used (such as "ISO8859-1", "cp850",
       "koi8-r", "sjis", "utf8", etc.), for the currency string, for the radix
       character used between the integer and the fractional part of decimal
       numbers (yes, this is redundant with POSIX::localeconv())

           YESSTR YESEXPR NOSTR NOEXPR

       for the affirmative and negative responses and expressions, and

           ERA ERADFMT ERADTFMT ERATFMT

       for the Japanese Emperor eras (naturally only defined under Japanese
       locales).

       See your langinfo(3) for more information about the available con-
       stants.  (Often this means having to look directly at the langinfo.h C
       header file.)

       Note that unfortunately none of the above constants are guaranteed to
       be available on a particular platform.  To be on the safe side you can
       wrap the import in an eval like this:

           eval {
               require I18N::Langinfo;
               I18N::Langinfo->import(qw(langinfo CODESET));
               $codeset = langinfo(CODESET()); # note the ()
           };
           if (!$@) { ... failed ... }

       EEXXPPOORRTT

       Nothing is exported by default.

       The langinfo() is just a wrapper for the C nllanginfo() interface.
