WordPress at a glance
function is not described

get_locale_stylesheet_uri() WP 2.1.0

Retrieves the localized stylesheet URI.

The stylesheet directory for the localized stylesheet files are located, by default, in the base theme directory. The name of the locale file will be the locale followed by '.css'. If that does not exist, then the text direction stylesheet will be checked for existence, for example 'ltr.css'.

The theme may change the location of the stylesheet directory by either using the stylesheet_directory_uri or locale_stylesheet_uri filters.

If you want to change the location of the stylesheet files for the entire WordPress workflow, then change the former. If you just have the locale in a separate folder, then change the latter.
