Read up un 'stat', 'lstat' for information about files and directories

make sure that you link with libc.

Then read the paragraph about 'scandir' if you use Unix or 
'FindFirstFile'/'FindNextFile' on Windows

int fl_filename_isdir(const char* n) {
   struct stat    s;

#ifdef WIN32
   char        fn[1024];
   int        length;
   // This workaround brought to you by the fine folks at Microsoft!
   // (read lots of sarcasm in that...)
   length = strlen(n);
   if (length < (int)(sizeof(fn) - 1)) {
     if (length < 4 && isalpha(n[0]) && n[1] == ':' &&
         (isdirsep(n[2]) || !n[2])) {
       // Always use D:/ for drive letters
       fn[0] = n[0];
       strcpy(fn + 1, ":/");
       n = fn;
     } else if (length > 0 && isdirsep(n[length - 1])) {
       // Strip trailing slash from name...
       length --;
       memcpy(fn, n, length);
       fn[length] = '\0';
       n = fn;
     }
   }
#endif

   return !stat(n, &s) && (s.st_mode&0170000)==0040000;
}
