+===== $msgbuf(index) =====
+Get or set the character in the message buffer at the position index.
+The index has to be a positive integer or a variable holding such value.
+Note that the variable returns a clone of the character stored in a static buffer, copy it to another variable if you want to compare with another $msgbuf(index).
+The update is done directly and immediately in the message buffer -- use it with care!
+Example of usage:
+<code c>
+if ($msgbuf(20)=="V") {
+    $msgbuf(20) = "v";
+}
+</code>

+==== $hfitname(iname) ====
+The header name of the header field iterator.

+<code c>

+        xlog("hdr[$hfitname(i1)] is: $hfitbody(i1)\n");
+    }
+    hf_iterator_end("i1");
+</code>
+====== $hfitbody(iname) ======
+The header body of the header field iterator.
+Example:
+<code c>
+    hf_iterator_start("i1");
+    while(hf_iterator_next("i1")) {
