<div class="textblock"><p>Mutex. </p>
<h1><a class="anchor" id="PIMutex_sec0"></a>
Synopsis</h1>
<p>PIMutex provides synchronization blocks between several threads. Using mutex guarantees execution of some code only one of threads. Mutex contains logic state and functions to change it: <em><a class="el" href="class_p_i_mutex.html#aa571ad61ee7bd5fcf60f6f5032a16441" title="Lock mutex. ">lock()</a></em>, <em><a class="el" href="class_p_i_mutex.html#aae483d17150e38436ca25a1bd26b04c2" title="Unlock mutex. ">unlock()</a></em> and <em><a class="el" href="class_p_i_mutex.html#a5c4ed063c5c7d7ee94ff3402d320851a" title="Try to lock mutex. ">tryLock()</a></em>.</p>
<h1><a class="anchor" id="PIMutex_sec1"></a>
Usage</h1>
<p>Block of code that should to be executed only one thread simultaniously should to be started with <em><a class="el" href="class_p_i_mutex.html#aa571ad61ee7bd5fcf60f6f5032a16441" title="Lock mutex. ">lock()</a></em> and ended with <em><a class="el" href="class_p_i_mutex.html#aae483d17150e38436ca25a1bd26b04c2" title="Unlock mutex. ">unlock()</a></em>. </p><div class="fragment"><div class="line">mutex.lock();</div>
<div class="line"><span class="comment">// ... your code here</span></div>
<div class="line">mutex.unlock();</div>
