Learn the default language on Linux

Is there a way to learn the default language of a Linux system with C? Is there a POSIX API for this? For instance. I would like to have a string in a readable format, for example, “German” or “German” in the German system “French” or “franc” in the French system, etc. Is there something like this?

Thank!

Typically, an environment variable LANGcontains this information in the format "de_DE.UTF-8".

You can get it using the function getenv.

EDIT:

For more complex internationalization, you may need to learn gettext .

At least gettext , the most popular translation structure in a Unix-like OS, is guided by these rules.
