- Like ``y#``, but accepts any object which implements the read-write buffer
- interface. The :ctype:`char \*` variable is set to point to the first byte
- of the buffer, and the :ctype:`int` is set to the length of the buffer.

+ This format accepts any object which implements the read-write buffer
+ interface. It fills a :ctype:`Py_buffer` structure provided by the caller.
+ The buffer may contain embedded null bytes. The caller have to call
+ :cfunc:`PyBuffer_Release` when it is done with the buffer.
``es`` (:class:`str`) [const char \*encoding, char \*\*buffer]
This variant on ``s`` is used for encoding Unicode into a character buffer.
