Signals end of directory listing

注: Make sure the length of the string is greater than or equal to dwMaxFile.

注: If there are no more files to enumerate, WebFtpFindNextFile returns false and sets the variable to WEB_FTP_FA_NO_MORE_FILES.

  var
    hFtp : number;
    sFileName : string(MAX_PATH);
    nAttribute : number;
    nFiles : number;
    bOk : boolean; 
  begin
    WebFtpConnect(hFtp, "standardhost", WEB_PORT_FTP, "", "");
    nFiles := 0;
 
    // Custom directory list enumeration
    bOk := WebFtpFindFirstFile(hFtp, "", sFileName,
    MAX_PATH, nAttribute);
 
    while bOk do 
      write(sFileName); write(" "); write(nAttribute); 
      writeln;
      nFiles := nFiles + 1;
      bOk := WebFtpFindNextFile(hFtp, sFileName,
      MAX_PATH, nAttribute); 
    end;
 
    if nAttribute = WEB_FTP_FA_NO_MORE_FILES then 
      write(nFiles); write(" files found"); writeLn; 
    else 
      write("Error retrieving directory information!"); writeln; 
    end;
 
    // The following command does the same

    WebFtpShutdown(hFtp); 
  end TWebFtpListDir;
