For versions of Windows 10.0.10586 and later, the console is expected to be in ENABLE_VIRTUAL_TERMINAL_INPUT mode and the default method is called. For older versions of Windows, msvcrt.getwch() is used. If the received character is ``\x00`` or ``\xe0``, the next character is automatically retrieved. )à)rVTMODE_SUPPORTEDsuperrgetchmsvcrtgetwch)selfrtn __class__s l/var/dept/share/cheung/public_html/OutSchool/python/env/lib/python3.12/site-packages/blessed/win_terminal.pyrzTerminal.getchsG  ! !4.0 0mmo " " 6==?

This method is used by :meth:`inkey` to determine if a byte may be read using :meth:`getch` without blocking. This is implemented by wrapping msvcrt.kbhit() in a timeout. :arg float timeout: When ``timeout`` is 0, this call is non-blocking, otherwise blocking indefinitely until keypress is detected when None (default). When ``timeout`` is a positive number, returns after ``timeout`` seconds have elapsed (float). :rtype: bool :returns: True if a keypress is awaiting to be read on the keyboard attached to this terminal. rTg{Gz?F)timerkbhitsleep)rtimeoutends rrzTerminal.kbhit.sU"iikW\*||~"sTYY['8 JJt rcrtj|}t|j|jddS)a Return named tuple describing size of the terminal by ``fd``. :arg int fd: file descriptor queries for its window size. :rtype: WINSZ :returns: named tuple describing size of the terminal WINSZ is a :class:`collections.namedtuple` instance, whose structure directly maps to the return value of the :const:`termios.TIOCGWINSZ` ioctl return value.

This is a context manager for ``jinxed.w32.setcbreak()``. .. note:: You must explicitly print any user input you would like displayed. If you provide any kind of editing, you must handle backspace and other line-editing control functions in this mode as well! **Normally**, characters received from the keyboard cannot be read by Python until the *Return* key is pressed. Also known as *cooked* or *canonical input* mode, it allows the tty driver to provide line-editing before shuttling the input to your program and is the (implicit) default terminal mode set by most unix shells before executing programs.

Although both :meth:`break` and :meth:`raw` modes allow each keystroke to be read immediately after it is pressed, Raw mode disables processing of input and output. In cbreak mode, special input characters such as ``^C`` are interpreted by the terminal driver and excluded from the stdin stream. In raw mode these values are receive by the :meth:`inkey` method.
