//component (only) of the file.  Ie:
//
//char longFileName[_MAX_PATH + 1];
//getLongFileName(longFileName, sizeof(longFileName), "C:\\FOOBAR~1");
//
//Would put something like "FOOBARBAZ" (or whatever the long fn is) in
//longFileName.
//
//Note that, as far as I'm aware, if you're actually going to open the file,
//you need to use the alias (short) version; opening "C:\\FOOBARBAZ" won't
//work, while opening "C:\\FOOBAR~1" will.
