Howto get the language name for a given locale in linux


This is pretty much This question with a bit more information. My goal is to work out the languages installed in the system.

The following command

locale -a 

displays all the languages (in a format such as en_AU.utf8). This seems to correspond to the contents of /usr/lib/locale.

Furthermore, invoking

LANG=fr_FR.utf8 locale -ck LC_IDENTIFICATION

Gives information of that particular locale which includes the language name (Which in this case is French).

This seems to be the information contained in /usr/lib/locale/fr_FR.utf8/LC_IDENTIFICATION.

Is there a way (maybe an API call) to obtain this info? I looked at the source of the locale utility but it uses a private struct.


Solution

  • Thanks to Yasir. This is exactly what I wanted:

    #include <langinfo.h>
    
    char *s;
    s = getenv("LANG");
    if (s == NULL) 
        printf("LANG is not set");
    else {
        setlocale(LC_ALL, s);
        printf(nl_langinfo(_NL_IDENTIFICATION_LANGUAGE));
    }
