+    <h1 id="firstHeading" class="firstHeading">Static storage duration</h1>            <p>An object whose identifier is declared without the storage-class specifier <code>_Thread_local</code>, and either with external or internal <a href="storage_duration#Linkage" title="c/language/storage duration">linkage</a> or with the storage-class specifier <code>static</code>, has static storage duration. Its lifetime is the entire execution of the program and its stored value is initialized only once, prior to program startup.</p>
+<h3 id="Notes"> Notes</h3> <p>Since its stored value is initialized only once, an object with static storage duration can profile the invocations of a function.</p>
+<p>The other use of the keyword <code>static</code> is <a href="file_scope" title="c/language/file scope">file scope</a>.</p>
