    <ul>

    <li>
<p>
 <tt>alphaNumChar&nbsp;()</tt> 
</p>
</li>

        <ul>

  returns a random alphanumeric character. 
        </ul>


    <li class="gap">
<p>
 <tt>alphaNumString&nbsp;n</tt> 
</p>
</li>

        <ul>

  returns a string of length <tt>n</tt> of random alphanumeric   characters.  
        </ul>


    <li class="gap">
<p>
 <tt>rand&nbsp;()</tt> 
</p>
</li>

        <ul>

  returns the next pseudo-random number. 
        </ul>


    <li class="gap">
<p>
 <tt>seed&nbsp;()</tt> 
</p>
</li>

        <ul>

  returns a random word from <tt>/dev/random</tt>.  Useful as an arg to   <tt>srand</tt>.  If <tt>/dev/random</tt> can not be read from,    <tt>seed&nbsp;()</tt> returns <tt>NONE</tt>.  A call to <tt>seed</tt> may block   until enough random bits are available. 
        </ul>


    <li class="gap">
<p>
 <tt>srand&nbsp;w</tt> 
</p>
</li>

        <ul>

  sets the seed used by <tt>rand</tt> to <tt>w</tt>. 
        </ul>


    <li class="gap">
<p>
 <tt>useed&nbsp;()</tt> 
</p>
</li>

        <ul>

  returns a random word from <tt>/dev/urandom</tt>.  Useful as an arg to   <tt>srand</tt>.  If <tt>/dev/urandom</tt> can not be read from,    <tt>useed&nbsp;()</tt> returns <tt>NONE</tt>.  A call to <tt>useed</tt> will never   block -- it will instead return lower quality random bits. </ul>

</ul>
