24    <h2>Description</h2>
25    <div class="section">
26      <p>Gets the ID that uniquely identifies the current thread.</p><p>This differs from the <CODE><a href="../../../nn/os/Thread/GetCurrentId.html">Thread::GetCurrentId</a></CODE> function in that the value is cached in <CODE><a href="../../../nn/os/ThreadLocalStorage/Overview.html">ThreadLocalStorage</a></CODE>, so the ID can be obtained at a lower load.</p><p>When the current thread was not created by <CODE><a href="../../../nn/os/ManagedThread/Overview.html">ManagedThread</a></CODE> (for example, if it is a thread that was created by <CODE><a href="../../../nn/os/Thread/Overview.html">Thread</a></CODE>), this function returns <CODE>0</CODE>. Because <CODE>0</CODE> cannot be used as a valid ID, when this function returns <CODE>0</CODE> you can determine that the thread was not created by <CODE> <a href="../../../nn/os/ManagedThread/Overview.html">ManagedThread</a></CODE>.</p><!-- write here --></div>
