How to use C++ getopt_long() if I have more than 26 options?
<p>This is a rather hypothetical question, but let's say I have 3 long parameters that begin with the same letter. </p>

<pre><code>--parse or -p
--prune or -r
--pivot or -i
</code></pre>

<p>Eventually I'll start running out of single letters that make sense, more over, it's hard assign something meaningful in <a href="http://www.gnu.org/s/hello/manual/libc/Getopt-Long-Option-Example.html#Getopt-Long-Option-Example" rel="nofollow">GNU getopt_long()</a> configuration.</p>

<pre><code>{"parase", no_argument,       0, 'p'},
{"prune",  no_argument,       0, 'r'},
{"pivot",  required_argument, 0, 'i'}
</code></pre>

<p>What is the best practice in these situations?</p>
