<ul>
<li>
<p>
<tt>alphaNumChar ()</tt>
</p>
</li>
<ul>
returns a random alphanumeric character.
</ul>
<li class="gap">
<p>
<tt>alphaNumString n</tt>
</p>
</li>
<ul>
returns a string of length <tt>n</tt> of random alphanumeric characters.
</ul>
<li class="gap">
<p>
<tt>rand ()</tt>
</p>
</li>
<ul>
returns the next pseudo-random number.
</ul>
<li class="gap">
<p>
<tt>seed ()</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 ()</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 w</tt>
</p>
</li>
<ul>
sets the seed used by <tt>rand</tt> to <tt>w</tt>.
</ul>
<li class="gap">
<p>
<tt>useed ()</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 ()</tt> returns <tt>NONE</tt>. A call to <tt>useed</tt> will never block -- it will instead return lower quality random bits. </ul>
