<p>Represents a mutex (mutual exclusion). </p>
<p>It can be used to protect data against shared access. Try to use <a class="el" href="classGlib_1_1Mutex_1_1Lock.html" title="Utility class for exception-safe mutex locking.">Mutex::Lock</a> instead of calling <a class="el" href="classGlib_1_1Mutex.html#abd565d2c03dbd7526729b8e56ecc675e" title="Locks the mutex.">lock()</a> and <a class="el" href="classGlib_1_1Mutex.html#a254d550a0e2197d46fa7268475f19824" title="Unlocks the mutex.">unlock()</a> directly&#160;-- it will make your life much easier.</p>
