Save all file names in a directory to a vector
<p>I need to save all ".xml" file names in a directory to a vector.  To make a long story short, I cannot use the dirent API.  It seems as if C++ does not have any concept of "directories".</p>

<p>Once I have the filenames in a vector, I can iterate through and "fopen" these files.</p>

<p>Is there an easy way to get these filenames at runtime?  </p>
