+ <h4 class="subsection">Running Hooks</h4> <p>In this section, we document the <code>run-hooks</code> function, which is used to run a normal hook. We also document the functions for running various kinds of abnormal hooks. </p> <dl> <dt id="run-hooks">Function: <strong>run-hooks</strong> <em>&amp;rest hookvars</em>
+</dt> <dd>
+<p>This function takes one or more normal hook variable names as arguments, and runs each hook in turn. Each argument should be a symbol that is a normal hook variable. These arguments are processed in the order specified. </p> <p>If a hook variable has a non-<code>nil</code> value, that value should be a list of functions. <code>run-hooks</code> calls all the functions, one by one, with no arguments. </p> <p>The hook variable’s value can also be a single function—either a lambda expression or a symbol with a function definition—which <code>run-hooks</code> calls. But this usage is obsolete. </p> <p>If the hook variable is buffer-local, the buffer-local variable will be used instead of the global variable. However, if the buffer-local variable contains the element <code>t</code>, the global hook variable will be run as well. </p>
