"Certain objects available in Python wrap access to an underlying memory "
"array or *buffer*. Such objects include the built-in :class:`bytes` and :"
"class:`bytearray`, and some extension types like :class:`array.array`. Third-"
"party libraries may define their own types for special purposes, such as "
"image processing or numeric analysis."

"While each of these types have their own semantics, they share the common "
"characteristic of being backed by a possibly large memory buffer. It is "
"then desirable, in some situations, to access that buffer directly and "
"without intermediate copying."

msgstr

#:
../../c-api/buffer.rst:29
msgid
""
"on the producer side, a type can export a
\"
buffer interface
\"
which allows "
"objects of that type to expose information about their underlying buffer. "
"This interface is described in the section :ref:`buffer-structs`; for Python "
"see :ref:`python-buffer-protocol`."
msgstr
""
#:
../../c-api/buffer.rst:34

""
"on the consumer side, several means are available to obtain a pointer to the "
"raw underlying data of an object (for example a method parameter). For "
"Python see :class:`memoryview`."
msgstr
""

../../c-api/buffer.rst:38

"Simple objects such as :class:`bytes` and :class:`bytearray` expose their "

"through the buffer interface can be written to a file. While :meth:`!write` "
"only needs read-only access to the internal contents of the object passed to "
"it, other methods such as :meth:`~io.BufferedIOBase.readinto` need write "
"access to the contents of their argument. The buffer interface allows "
"objects to selectively allow or reject exporting of read-write and read-only "
