- * Using UniqueFd:
- * 1. Create UniqueFd object:
- *    auto fd_obj = UniqueFd(open("SomeFile", xxx));
- *
- * 2. Check whether the fd_obj is empty:
- *    if (!fd_obj) { return -errno; }
- *
- * 3. Accessing the file descriptor:
- *    int ret = read(fd_obj.Get(), buf, buf_size);
- *
- * 4. Closing the file:
- *    FD will be closed once execution leaves fd_obj scope (on any return,
- *    exception, destruction of class/struct where object is member, etc.).
- *    User can also force closing the fd_obj by calling:
- *      fd_obj = UniqueFd();
- *      // fd is closed and fd_obj is empty now.
- *
- * 5. File descriptor may be transferred to the code, which will close it after
- *    using. This can be done in 2 ways:
- *    a. Duplicate the fd, in this case both fds should be closed separately:
- *      int out_fd = dup(fd_obj.Get();
- *      ...
- *      close(out_fd);
- *    b. Transfer ownership, use this method if you do not need the fd anymore.
- *      int out_fd = fd_obj.Release();
- *      // fd_obj is empty now.
- *      ...
- *      close(out_fd);
- *
- * 6. Transferring fd into another UniqueFD object:
- *    UniqueFd fd_obj_2 = std::move(fd_obj);
- *    // fd_obj empty now
