<h1>NLMISC::CUnfairMutex 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>
Classic mutex implementation (not necessarly fair) Don't assume the mutex are recursive (ie don't call <a class="el" href="a03629.html#NLMISC_1_1CUnfairMutexa2">enter()</a> several times on the same mutex from the same thread without having called <a class="el" href="a03629.html#NLMISC_1_1CUnfairMutexa3">leave()</a>) ; and don't assume either the threads are woken-up in the same order as they were put to sleep !<p>
Windows: uses Mutex, cannot be shared among processes. Linux: uses PThread POSIX Mutex, cannot be shared among processes.<p>
