-<p>Support for the Librt library on the Symbian platform enables
-you to port Librt-based applications onto the Symbian platform quickly and

-the Librt functionality and your code must link to <filepath>librt.lib</filepath>. </p> <p> <b>Important:</b> Your

-must link to <filepath>librt.dll</filepath> prior to all other libraries in
