For my front-end written in C++ I'm trying to figure out how to place the

programmer on the list willing and able to help me with this one? I've been
Googling for about an hour trying to find an answer, but no luck sofar.
See attached, but what look for the UNIX Programming FAQ - it discusses
reading directories in good detail.
I pulled this from some WxWindows code I've written, so it may have a wx*
datatype or two. I couldn't see any with a quick look, but the compiler
will be the final arbiter.
