我dirent.h
用来递归地读取目录中的文件。在我的Debian GNU/Linux 7 (wheezy)
机器上它可以正常工作,但是在Ubuntu 12.04 LTS
服务器上它会将所有文件读取为 DT_UNKOWN!
if ((dir = opendir (input_dir)) != NULL)
{
while ((ent = readdir (dir)) != NULL)
{
// cat dir path to file
char full_file_path[FILE_NAME_LENGTH];
strcpy (full_file_path, input_dir);
strcat (full_file_path, "/");
strcat (full_file_path, ent->d_name);
// if "." or "..", skip it
if (!strcmp (ent->d_name, ".") || !strcmp (ent->d_name, ".."));
// if a regular file, process it
else if (ent->d_type == DT_REG)
{
process_file (full_file_path, f_out, z, ws);
}
// if a directory, recurse through it
else if (ent->d_type == DT_DIR)
{
// add '/' to the end of the directory path
process_directory (full_file_path, f_out, z, ws);
}
else
{
printf ("%s is neither a regular file nor a directory!\n",
full_file_path);
}
}
}
