NL_LANGINFO(3)             Library Functions Manual             NL_LANGINFO(3)

NAME
     nl_langinfo, nl_langinfo_l – language information

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <langinfo.h>

     char *
     nl_langinfo(nl_item item);

     #include <langinfo.h>
     #include <xlocale.h>

     char *
     nl_langinfo_l(nl_item item, locale_t loc);

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 manifest constant names and values of item
     are defined in <langinfo.h>.

     Calls to setlocale() with a category corresponding to the category of
     item, or to the category LC_ALL, may overwrite the buffer pointed to by
     the return value.

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

EXAMPLES
     For example:

           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.

     While the nl_langinfo() function uses the current locale, the
     nl_langinfo_l() function may be passed a locale directly. See xlocale(3)
     for more information.

     Specification (“SUSv2”).
