Re: Scan Directory

Hi,

It is platform specific however differentiating between unix/linux and
windows will cover most systems. Here is some code I use to read directories
on unix/linux/windows:

You need dirent.h header on unix/linux systems, I use WIN32 macro to
differentiate between the two

  }
  while( FindNextFile( hFind, &FindFileData ) );
     FindClose(hFind);

  }

#endif
 return RetVal;
