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.
