-the lifetime of this object.  You won't have to release any memory yourself.
-The only exceptions are ``es``, ``es#``, ``et`` and ``et#``.

-:c:func:`PyBuffer_Release` after you have finished processing the data (or
-in any early abort case).
-
 Unless otherwise stated, buffers are not NUL-terminated.
 
-Some formats require a read-only :term:`bytes-like object`, and set a
-pointer instead of a buffer structure.  They work by checking that
-the object's :c:member:`PyBufferProcs.bf_releasebuffer` field is ``NULL``,

+
