title: strpos in Emacs Lisp
body: <p>Is there a  native Emacs Lisp function that behaves like <a href="http://php.net/manual/en/function.strpos.php" rel="nofollow"><code>strpos()</code> in PHP</a>? It should return the position of first occurrence of the given string in current buffer. Function <code>search-forward</code> is nice, but it modifies the character position.</p>
