    Giá trị trả về. Hàm này trả về một mảng chứa các mục sau.
     

    • hết giờ. Đó là một mục kiểu boolean và TRUE nếu luồng đã hết thời gian chờ
    • bị chặn. Đây là một mục kiểu boolean và là True nếu luồng đang ở chế độ IO chặn
    • eof[bool] Nó là tùy chọn. Đó là True nếu luồng đạt đến ở cuối tệp
    • unread_bytes. Số byte trong bộ đệm trong
    • stream_type. Nó được sử dụng để chỉ định việc thực hiện luồng
    • trình bao bọc_type. Nó được sử dụng để chỉ định lớp triển khai trình bao bọc giao thức
    • trình bao bọc_data. Đó là một dữ liệu cụ thể được đính kèm với luồng này
    • cách thức. Đây là loại quyền truy cập cần thiết cho luồng này
    • có thể tìm được. Đó là sự thật khi luồng hiện tại tìm kiếm
    • nước tiểu. Mã định danh tài nguyên thống nhất do người dùng cung cấp
