The <CODE><a href="../../../nn/os/WaitObject/WaitAny.html">WaitAny</a></CODE> and <CODE><a href="../../../nn/os/WaitObject/WaitAll.html">WaitAll</a></CODE> functions allow you to wait for multiple <CODE><a href="../../../nn/os/WaitObject/Overview.html">WaitObjects</a></CODE> simultaneously. These <CODE>Wait</CODE> operations are "released" automatically by state changes in the objects being waited on. However, the "release" behavior for a <CODE>Wait</CODE> operation varies depending on the derived class. Some derived classes define their own functions whose names indicate the specific behavior of their <CODE>Wait</CODE> operations.</p><p>Threads that have carried out a <CODE>Wait</CODE> operation are blocked until the wait is released, thereby yielding the CPU resources to other threads.</p><p>This class cannot be instantiated directly. Use derived classes instead.</p><!-- write here --></div> 63 <a name="function" id="function"> 64<h2>Member Functions</h2> 65 <div class="section"> 66 <table class="members"> 67 <tr> 68 <td width="100"> </td> 69 <th> 70<a href="../../../nn/os/WaitObject/WaitOne.html"><CODE>WaitOne</CODE></a> 71 </th> 72<td>Waits for a single instance object.</td> 73 </tr> 74 <tr> 75 <td width="100"> 76<span class="static_style" title="static">S</span> </td> 77 <th> 78<a href="../../../nn/os/WaitObject/WaitAll.html"><CODE>WaitAll</CODE></a> 79 </th> 80<td>Waits for all objects.</td> 81 </tr> 82 <tr> 83 <td width="100"> 84<span class="static_style" title="static">S</span> </td> 85 <th> 86<a href="../../../nn/os/WaitObject/WaitAny.html"><CODE>WaitAny</CODE></a> 87 </th> 88<td>Waits for any single object.</td> 89 </tr> </table> 90 </div> 91 </a> 92<h2>Class Hierarchy</h2> 93 <div class="section"> 94<p class="hierarchy"><span>ADLFireWall::NonCopyable</span><br /> <a href="../../../nn/os/HandleObject/Overview.html">nn::os::HandleObject</a><br /> <b>nn::os::WaitObject</b> 95 </p> 96 </div> 97<h2>Revision History</h2> 98 <div class="section"> 99 <dl class="history"> 100 <dt>2010/01/07</dt> 101<dd>Initial version.<br /> 102 </dd> 103 </dl> 104 </div> 105 <hr><p>CONFIDENTIAL</p></body> 106</html>
