   <b>Description:</b>
   <ul>
     <p>
       <code>pipe()</code> creates a pair of file descriptors, pointing to a pipe inode, and
-      places them in the array pointed to by <code>filedes</code>.
+      places them in the array pointed to by <code>fd</code>.
-      <code>filedes[0]</code> is for reading, <code>filedes[1]</code> is for writing.
+      <code>fd[0]</code> is for reading, <code>fd[1]</code> is for writing.
     </p>
   </ul>
 </p>
 <p>
   <b>Input Parameters:</b>
   <ul>
-    <li><code>filedes[2]</code>.  The user provided array in which to catch the pipe file descriptors.</li>
+    <li><code>fd[2]</code>.  The user provided array in which to catch the pipe file descriptors.</li>
   </ul>
