    //  Note: It may be tempting to call MGetFiles(pattern,localDir)
    //  followed by a call to DeleteMatching(pattern), however,
    //  if new files are uploaded to the FTP server while MGetFiles
    //  is running, those files will be deleted by DeleteMatching.

    //  Instead, it's best to set the ListPattern and then iterate
    //  over each file...

    //  Set the ListPattern = "*.xml" to match all XML files.
    CkFtp2_putListPattern(ftp,"*.xml");

    //  NumFilesAndDirs contains the number of files and sub-directories
    //  matching the ListPattern in the current remote directory.
    //  The first time it is accessed after changing ListPattern,
    //  or after calling ChangeRemoteDir, a snapshot of the directory
    //  listing is fetched and saved in memory. During this loop,
    //  the value of NumFilesAndDirs will not change.

            printf("%s\n",fname);

            //  Download the file into the current working directory.
            success = CkFtp2_GetFile(ftp,fname,fname);
