If the Examine/ExNext/ExAll functions need to restart directory scanning, the cache maintained by the smbfs directory reader is now always cleared. Removed the directory cache expiration time feature, along with the just-introduced CACHEEXPIRES option. The context in which the expiration time was used did not justify it as a feature. It looked more like a bug... Rewrote the smba_readdir() function to perform its only task in a much simpler manner. It now either fills the directory cache or retrieves the cache entries to be delivered to the caller, resuming the retrieval at a predefined position if required.
