this is out of my mp3 server, it scans a dirctory for all .MP3 files, hope this helps

void Mp3FileStore::get_tracks(char *path, long album_id)
{
     assert(path != NULL);

     struct _finddata_t ff;
     long fhandle;
     char spath[256], fname[_MAX_FNAME], ext[_MAX_EXT];

     /* make a path with wild card for .mp3 on the end */
     sprintf(spath,"%s\\*.*",path);
     /* open the direcory */
     if((fhandle = _findfirst(spath,&ff)) != -1)
     {
          /* loop through each entry */
          while(!_findnext(fhandle,&ff))
          {    
               /* is it a file */
               if(ff.attrib ^ _A_SYSTEM)
               {
                    /* extract the track name */
                    _splitpath(ff.name,NULL,NULL,fname,ext);          
                    if(!stricmp(ext,".mp3"))
                    {      
                         add_track_to_array(fname,album_id);
                    }
               }
          }
          close(fhandle);
     }

If your compiler supports it (virtually all compilers do) take a look at directory streams, in the header <dirent.h>,

#include <stddef.h>
#include <stdio.h>
#include <sys/types.h>
#include <dirent.h>

int
main (void)
{
  DIR *dp;
  struct dirent *ep;

  dp = opendir ("./");
  if (dp != NULL)
    {
      while (ep = readdir (dp))
        puts (ep->d_name);
      (void) closedir (dp);
    }
  else
    puts ("Couldn't open the directory.");

  return 0;
}

Take a look at the Boost Library at http://www.boost.org

Within the library is a very easy to use, portable and in the running for inclusion within the next C++ standard library.

It includes iterators to directory contents so you can use the std::library without any wrapping whatso ever.

If you have problems using this just ask.

(Theres lots of other good stuff in the library as well)

Regards,

Vic

Hi vickirk, welcome to EE.

the solution i proposed will only work on a windows platform, but if thats all you want then cool, KangaRoo's solution will work on linux/unix but i can not find that function on VC++

KangaRooCommented:
VC++ is one I don't have :-/ Borlands compilers do implement directory as well as MingW32 Cygwin GCC (apart from just Linux/Unix). So, it depends on which compile/OS, again.
