  Further information
 
 1. The language code is used to select the locale directory in which catalog files are searched from. During the library initialisation the language is set according to the current system settings.
 
 2. If
 NULL is used as the language code the function returns the current language. If an empty string is given then the language is set to the system default setting (as after library initialisation).
 
 3. Special language names
 "C",
 "POSIX" as well as
 "en" disable translation (since initial messages are written in English).
 
 4. All loaded message catalogs are unloaded when a call to this routine modifies the current language.
