Getting entry type with scandir() on FAT drive?

thomas_fogh · 07-29-2007, 11:06 AM

I need to create a file/dir list sorted alphabetically and with directories first.
That was pretty easy with scandir() but it doesn't work with fat and ntfs drives

I thought about using stat() but with scandir() I don't get the full path.
Any ideas how to proceed?

Code:

int file_select(const struct dirent* entry)
{
  if ( (strcmp(entry->d_name, ".") == 0) ||
       (strcmp(entry->d_name, "..") == 0) ||
       ((entry->d_type != DT_DIR) &&
	(entry->d_type != DT_REG)) )
    return 0;
  else
    return 1;
}

int file_sort(const struct dirent** d1, const struct dirent** d2)
{
  if ((*d1)->d_type == DT_DIR && (*d2)->d_type == DT_REG)
    return -1;
  else if ((*d1)->d_type == DT_REG && (*d2)->d_type == DT_DIR)
    return 1;
  else return strcmp((*d1)->d_name, (*d2)->d_name);
}

void print_dirs(char* dir)
{
  struct dirent **files;
  int count, i;

  count = scandir(dir, &files, file_select, file_sort);

  for (i = 0; i < count; i++) {
    if (files[i]->d_type == DT_DIR) {
      char* temp_name = malloc(strlen(dir)+strlen(files[i]->d_name)+2);
      strcpy(temp_name, dir);
      strcat(temp_name, "/");
      strcat(temp_name, files[i]->d_name);
      printf("[%s]\n", temp_name);
      print_dirs(temp_name);
      free(temp_name);
    } else if (files[i]->d_type == DT_REG) {
      printf("%s\n", files[i]->d_name);
    }
    free(files[i]);
  }
}

int main(int argc, char** argv)
{
  print_dirs("/svn");
}
