+//- converts short filename to long filenames (TODO: not yet done here!)
+//- if lpszShortPath 0 or cchBuffer too small -> return required length
+//  (INCLUDING 0 terminator)
+//- if lpszLongPath == NULL -> ERROR_INVALID_PARAMETER (return 0)
+//- if lpszLongPath empty -> proceed as if nothing is wrong
+//- does NOT clear the last error if successful!
+//- if successful -> return length of string (excluding 0 terminator)
