Returns the value associated with key under groupName translated in the given locale if available. If locale is Nothing then the current locale is assumed.

If locale is to be non-Nothing, or if the current locale will change over the lifetime of the KeyFile, it must be loaded with KeyFileFlagsKeepTranslations in order to load strings for all locales.

If key cannot be found then Nothing is returned and error is set to G_KEY_FILE_ERROR_KEY_NOT_FOUND. If the value associated with key cannot be interpreted or no suitable translation can be found then the untranslated value is returned.

Returns: a newly allocated Nothing-terminated string array or Nothing if the key isn't found. The string array should be freed with strfreev. (Can throw GError)

Returns the values associated with key under groupName translated in the given locale if available. If locale is Nothing then the current locale is assumed.

If locale is to be non-Nothing, or if the current locale will change over the lifetime of the KeyFile, it must be loaded with KeyFileFlagsKeepTranslations in order to load strings for all locales.

If key cannot be found then Nothing is returned and error is set to G_KEY_FILE_ERROR_KEY_NOT_FOUND. If the values associated with key cannot be interpreted or no suitable translations can be found then the untranslated values are returned. The returned array is Nothing-terminated, so length may optionally be Nothing.

Since: 2.6
