Getting a list of available locales

[Anssi Hannula]

Hi!

The VDR project (GPL set-top-box style software) has an option in the 
setup menu to change the language (as commercial devices do). Previously 
a custom translation scheme was used, but using gettext would be 
preferable for many reasons.

However, having the ability to switch language during run-time is 
problematic; setlocale() can only be called with specific locale names, 
that vary depending on system. The correct one could be "fi", "fi_FI", 
address@hidden" etc.

It would help if there was some call that would return all the installed 
locales in "locale -a" style.
Even better would be a call that returns a list of the locales that have 
a translation for a given text domain.

Is providing such a function a possibility? Should it be implemented in 
gettext, or glibc?

Or is there another option we have missed?
