PROLOG

       This  manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (consult the correspond-
       ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

NAME

       nl_langinfo - language information

SYNOPSIS

       #include <langinfo.h>

       char *nl_langinfo(nl_item item);

DESCRIPTION

       The nl_langinfo() function shall return a pointer to a string containing information relevant to the particular language or  cultural  area
       defined in the program's locale (see <langinfo.h>).  The manifest constant names and values of item are defined in <langinfo.h>.  For exam-
       ple:

	      nl_langinfo(ABDAY_1)

       would return a pointer to the string "Dom" if the identified language was Portuguese, and "Sun" if the identified language was English.

       Calls to setlocale() with a category corresponding to the category of item (see <langinfo.h>), or to the category LC_ALL  ,  may  overwrite
       the array pointed to by the return value.

       The nl_langinfo() function need not be reentrant. A function that is not required to be reentrant is not required to be thread-safe.

RETURN VALUE

       In  a  locale  where langinfo data is not defined, nl_langinfo() shall return a pointer to the corresponding string in the POSIX locale. In
       all locales, nl_langinfo() shall return a pointer to an empty string if item contains an invalid setting.

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

ERRORS

       No errors are defined.

       The following sections are informative.

EXAMPLES

   Getting Date and Time Formatting Information
       The following example returns a pointer to a string containing date and time formatting information, as defined in the LC_TIME category	of
       the current locale.

	      #include <time.h>
	      #include <langinfo.h>
	      ...
	      strftime(datestring, sizeof(datestring), nl_langinfo(D_T_FMT), tm);
	      ...

APPLICATION USAGE

       The array pointed to by the return value should not be modified by the program, but may be modified by further calls to nl_langinfo().

RATIONALE

       None.

FUTURE DIRECTIONS

       None.

NAME

       nl_langinfo - Returns language or cultural data defined in the current locale

LIBRARY

       Standard C Library (libc)

SYNOPSIS

       #include <langinfo.h>

       char *nl_langinfo(
	       nl_item item);

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       nl_langinfo(): XSH5.0

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

PARAMETERS

       Specifies a constant name or value.

DESCRIPTION

       The  nl_langinfo()  function  returns  a  pointer  to  a string containing information relevant to the particular language or cultural area
       defined in the program's locale.  The constant names and values that are valid for the item parameter are defined in the langinfo.h  header
       file.

       The  array  pointed to by the return value may contain static data that is overridden on the next call to nl_langinfo().  This array should
       not be modified by the application, only by further calls to nl_langinfo().

       The XSH specification does not require the nl_langinfo() function to be re-entrant.

EXAMPLES

       The following example returns a pointer to the abbreviated name of the first day of the week in the current locale:

       nl_langinfo(ABDAY_1)

       This function call would return a pointer to the string "Dom" if the identified language was Portuguese, "Sun" if the  identified  language
       was English, and so on.

RETURN VALUES

       In  a  locale where langinfo data is not defined, the nl_langinfo() function returns a pointer to the corresponding string in the POSIX (C)
       locale.	In all locales, the nl_langinfo() function returns a pointer to an empty string if the item parameter contains an invalid setting.
