+<h1>NLMISC::CSharedMutex Class Reference</h1><code>#include &lt;<a class="el" href="a06088.html">mutex.h</a>&gt;</code>
+<p>
+<hr><a name="_details"></a><h2>Detailed Description</h2>
+Windows: uses Mutex, the handle can't be shared among processes, but the mutex still can be be shared by passing a common object name to createByName() / <a class="el" href="a03383.html#NLMISC_1_1CSharedMutexa0">createByKey()</a>. Note: the mutex must be explicitely destroyed by calling <a class="el" href="a03383.html#NLMISC_1_1CSharedMutexa2">destroy()</a>.<p>
