<entry><p>This constant represents the timeout value for each client in microseconds.
The shutdown server uses it and <codeph>KShtdwnTimeoutBase</codeph> to calculate
the shutdown timer. The timeout is calculated as </p> <codeblock id="GUID-B040CD7C-5674-5983-B5A4-649C2B941732" xml:space="preserve">KShtdwnTimeoutBase + KShtdwnTimeoutClient * numClients</codeblock> <p>where <codeph>numClients</codeph> is the number of connecting clients. </p> </entry>

execute the shutdown if the timer expires or all clients re-register. </p> </li>

<p> <codeph>KShtdwnTimeoutClient</codeph> is an internal constant and should
not be directly modified. Device creators who wish to alter <codeph>KShtdwnTimeoutClient</codeph> and <codeph>KShtdwnTimeoutBase</codeph> should
define these ROM build-time macros in their product HRH or IBY files: </p>
