get_locale_string

Returns the value associated with key under group_name translated in the given locale if available.

If locale is `C` then the untranslated value is returned (since GLib 2.84).

If locale is `NULL` then the current locale is assumed.

If locale is to be non-`NULL`, or if the current locale will change over the lifetime of the [struct@GLib.KeyFile], it must be loaded with [flags@GLib.KeyFileFlags.KEEP_TRANSLATIONS] in order to load strings for all locales.

If key cannot be found then [error@GLib.KeyFileError.KEY_NOT_FOUND] is returned. If the value associated with key cannot be interpreted or no suitable translation can be found then the untranslated value is returned.

Parameters:

this	a key file
group_name	a group name
key	a key
locale	a locale identifier or `NULL` to use the current locale

Returns:

a newly allocated string or `NULL` if the specified key cannot be found.
