conversion between char* and FILE type
<p>I'm using c++ for a project now. I'm trying to use a library which has a function like this:</p>

<pre><code>function (FILE* input, FILE* output)
</code></pre>

<p>but I don't want to have any files generated in the process. I hope to use as char* type variables to replace the "input", "output" parameter.</p>

<p>How could I do this?</p>
