"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."
msgstr ""

#: ../../c-api/buffer.rst:24
msgid ""
"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

"Python provides such a facility at the C level in the form of the "
":ref:`buffer protocol <bufferobjects>`.  This protocol has two sides:"
msgstr ""

#: ../../c-api/buffer.rst:34
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`;"
msgstr ""

#: ../../c-api/buffer.rst:38
msgid ""
"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)."
msgstr ""

#: ../../c-api/buffer.rst:41
msgid ""
"Simple objects such as :class:`bytes` and :class:`bytearray` expose their "
"underlying buffer in byte-oriented form.  Other forms are possible; for "
"example, the elements exposed by an :class:`array.array` can be multi-byte "
"values."
msgstr ""

#: ../../c-api/buffer.rst:45
msgid ""
"An example consumer of the buffer interface is the "
":meth:`~io.BufferedIOBase.write` method of file objects: any object that can"
" export a series of bytes 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 buffers."
msgstr ""

msgid ""
"Buffer structures (or simply \"buffers\") are useful as a way to expose the "
"binary data from another object to the Python programmer.  They can also be "
"used as a zero-copy slicing mechanism.  Using their ability to reference a "
"block of memory, it is possible to expose any data to the Python programmer "
"quite easily.  The memory could be a large, constant array in a C extension,"
" it could be a raw block of memory for manipulation before passing to an "
"operating system library, or it could be used to pass around structured data"
" in its native, in-memory format."
msgstr ""

msgid ""
"Contrary to most data types exposed by the Python interpreter, buffers are "
"not :c:type:`PyObject` pointers but rather simple C structures.  This allows"
