SUMMARY
=======

The documentation for CFileFind::FindNextFile, CFtpFileFind::FindNextFile, and
CGopherFileFind::FindNextFile in the Class Library Reference with Visual C++ is
incorrect. The documentation states:

  Return Value

  Nonzero if successful; otherwise 0. To get extended error information,
  call the Win32 function GetLastError.

The documentation should read:

  Return Value

  Nonzero if there are more files; zero if the file found is the last one
  in the directory or if an error occurred. To get extended error
  information, call the Win32 function GetLastError. If the file found
  is the last file in the directory, or if no matching files can be found,
  the GetLastError function returns ERROR_NO_MORE_FILES.

MORE INFORMATION
================

The code below shows how to use CFileFind::FindNextFile to find every file in a
directory.

Sample Code
-----------

     CFileFind finder;
     BOOL bWorking = finder.FindFile("*.*");
     while (bWorking)
     {
         bWorking = finder.FindNextFile();
         // Do processing here
     }
