"The first three of these functions described, :c:func:`PyArg_ParseTuple`, :c:"

"A format string consists of zero or more \"format units.\" A format unit "
"describes one Python object; it is usually a single character or a "
"parenthesized sequence of format units. With a few exceptions, a format "
"unit that is not a parenthesized sequence normally corresponds to a single "
"address argument to these functions. In the following description, the "
"quoted form is the format unit; the entry in (round) parentheses is the "
"Python object type that matches the format unit; and the entry in [square] "
"brackets is the type of the C variable(s) whose address should be passed."

msgstr ""
#: ../../c-api/arg.rst:37
msgid ""
"In general, when a format sets a pointer to a buffer, the buffer is managed "
"by the corresponding Python object, and the buffer shares the lifetime of "
"this object. You won't have to release any memory yourself. The only "
"exceptions are ``es``, ``es#``, ``et`` and ``et#``."
msgstr ""
#: ../../c-api/arg.rst:42
msgid ""
"However, when a :c:type:`Py_buffer` structure gets filled, the underlying "
"buffer is locked so that the caller can subsequently use the buffer even "
"inside a :c:type:`Py_BEGIN_ALLOW_THREADS` block without the risk of mutable "
"data being resized or destroyed. As a result, **you have to call** :c:func:"
"`PyBuffer_Release` after you have finished processing the data (or in any "
"early abort case)."

msgstr ""
#: ../../c-api/arg.rst:51

"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*, which "
"disallows mutable objects such as :class:`bytearray`."
msgstr ""
#: ../../c-api/arg.rst:58
msgid ""
"For all ``#`` variants of formats (``s#``, ``y#``, etc.), the type of the "
"length argument (int or :c:type:`Py_ssize_t`) is controlled by defining the "
"macro :c:macro:`PY_SSIZE_T_CLEAN` before including :file:`Python.h`. If the "
"macro was defined, length is a :c:type:`Py_ssize_t` rather than an :c:type:"
"`int`. This behavior will change in a future Python version to only support :"
"c:type:`Py_ssize_t` and drop :c:type:`int` support. It is best to always "
