NAME
       nl_langinfo - query language and locale information

SYNOPSIS
       #include <langinfo.h>

       char *nl_langinfo(nl_item *item);

DESCRIPTION
       The  nl_langinfo  function  provides access to locale information in a more flexible way than localeconv(3) does. Individual and additional
       elements of the locale categories can be queried.

       Examples for the locale elements that can be specified in item using the constants defined in <langinfo.h> are:

       CODESET (LC_CTYPE)
	      Return a string with the name  of  the  character  encoding  used  in  the  selected  locale,  such  as  "UTF-8",  "ISO-8859-1",	or
	      "ANSI_X3.4-1968"	(better  known	as  US-ASCII). This is the same string that you get with "locale charmap". For a list of character
	      encoding names, try "locale -m", cf. locale(1).

       D_T_FMT (LC_TIME)
	      Return a string that can be used as a format string for strftime(3) to represent time and date in a locale-specific way.

       D_FMT (LC_TIME)
	      Return a string that can be used as a format string for strftime(3) to represent a date in a locale-specific way.

       T_FMT (LC_TIME)
	      Return a string that can be used as a format string for strftime(3) to represent a time in a locale-specific way.

       DAY_{1-7} (LC_TIME)
	      Return name of the n-th day of the week. [Warning: this follows the US convention DAY_1 = Sunday, not the  international	convention
	      (ISO 8601) that Monday is the first day of the week.]

       ABDAY_{1-7} (LC_TIME)
	      Return abbreviated name of the n-th day of the week.

       MON_{1-12} (LC_TIME)
	      Return name of the n-th month.

       ABMON_{1-12} (LC_TIME)
	      Return abbreviated name of the n-th month.

       RADIXCHAR (LC_NUMERIC)
	      Return radix character (decimal dot, decimal comma, etc.).

       THOUSEP (LC_NUMERIC)
	      Return separator character for thousands (groups of three digits).

       YESEXPR (LC_MESSAGES)
	      Return a regular expression that can be used with the regex(3) function to recognize a positive response to a yes/no question.

       NOEXPR (LC_MESSAGES)
	      Return a regular expression that can be used with the regex(3) function to recognize a negative response to a yes/no question.

       CRNCYSTR (LC_MONETARY)
	      Return  the currency symbol, preceded by "-" if the symbol should appear before the value, "+" if the symbol should appear after the
	      value, or "." if the symbol should replace the radix character.

       The above list covers just some examples of items that can be requested. For a more detailed list, please consult The GNU C Library  Refer-
       ence Manual.

RETURN VALUE
       If no locale has been selected for the appropriate category, nl_langinfo returns a pointer to the corresponding string in the "C" locale.

       If item is not valid, a pointer to an empty string is returned.

       This pointer may point to static data that may be overwritten on the next call to nl_langinfo or setlocale.
