<hr><a name="_details"></a><h2>Detailed Description</h2>
Implements a spin-loop to wait for the mutex to unlock. Since this class makes the thread wait in a tight spin-loop, it can cause the thread to remain busy while waiting and thus consume CPU cycles. For that reason, this mutex is best used only for very low-level resources - especially resources which do not require much CPU time to exercise. Rule of thumb: Use this only if all actions on the resource consume a very small number of CPU cycles. Otherwise, use the <a class="el" href="a00126.html">SleepLevelMutex</a> instead. <hr>The documentation for this class was generated from the following files:<ul>
<li><a class="el" href="a00158.html">LevelMutex.h</a><li><a class="el" href="a00157.html">LevelMutex.cpp</a></ul>
