Getting user's country and keyboard language

In order to present the proper menu text and some other aspects of the UI I am trying to get the current user's country and keyboard language.

I know the locale (via the env. variable) but I can't find a way to get these two pieces of info.

The code is in C for Mac OS X. I can use Co开发者_StackOverflowcoa API to get them but they need to be called from C. Any ideas?

Thank you!

Use CFLocaleCopyCurrent, CFLocaleGetValue and CFLocaleCopyPreferredLanguages (note that the preferred language may not match the locale's language). See the documentation.

Edit: ok, here's some sample code.

#include <CoreFoundation/CoreFoundation.h>
#include <stdio.h>

int main (int argc, char **argv)
{
    CFLocaleRef loc = CFLocaleCopyCurrent();
    CFStringRef countryCode = CFLocaleGetValue (loc, kCFLocaleCountryCode);
    CFStringRef countryName = CFLocaleCopyDisplayNameForPropertyValue (loc, kCFLocaleCountryCode, countryCode);
    CFShow(countryCode);
    CFShow(countryName);
    CFArrayRef langs = CFLocaleCopyPreferredLanguages();
    CFStringRef langCode = CFArrayGetValueAtIndex (langs, 0);
    CFStringRef langName = CFLocaleCopyDisplayNameForPropertyValue (loc, kCFLocaleLanguageCode, langCode);
    CFShow(langCode);
    CFShow(langName);
}
