msgid ":mod:`!fcntl` --- The ``fcntl`` and ``ioctl`` system calls"
msgstr ""

msgid ""
"This module performs file and I/O control on file descriptors. It is an "
"interface to the :c:func:`fcntl` and :c:func:`ioctl` Unix routines. See the :"
"manpage:`fcntl(2)` and :manpage:`ioctl(2)` Unix manual pages for full "
"details."

msgid ""
"All functions in this module take a file descriptor *fd* as their first "
"argument.  This can be an integer file descriptor, such as returned by ``sys."
"stdin.fileno()``, or an :class:`io.IOBase` object, such as ``sys.stdin`` "
"itself, which provides a :meth:`~io.IOBase.fileno` that returns a genuine "
"file descriptor."
msgstr ""

msgid ""
"Operations in this module used to raise an :exc:`IOError` where they now "
"raise an :exc:`OSError`."
msgstr ""

msgid ""
"The :mod:`!fcntl` module now contains ``F_ADD_SEALS``, ``F_GET_SEALS``, and "
"``F_SEAL_*`` constants for sealing of :func:`os.memfd_create` file "
"descriptors."
msgstr ""

msgid ""
"On macOS, the :mod:`!fcntl` module exposes the ``F_GETPATH`` constant, which "
"obtains the path of a file from a file descriptor. On Linux(>=3.15), the :"
"mod:`!fcntl` module exposes the ``F_OFD_GETLK``, ``F_OFD_SETLK`` and "
"``F_OFD_SETLKW`` constants, which are used when working with open file "
"description locks."
msgstr ""

msgid ""
"On Linux >= 2.6.11, the :mod:`!fcntl` module exposes the ``F_GETPIPE_SZ`` "
"and ``F_SETPIPE_SZ`` constants, which allow to check and modify a pipe's "
"size respectively."
msgstr ""

msgid ""
"On FreeBSD, the :mod:`!fcntl` module exposes the ``F_DUP2FD`` and "
"``F_DUP2FD_CLOEXEC`` constants, which allow to duplicate a file descriptor, "
"the latter setting ``FD_CLOEXEC`` flag in addition."
msgstr ""

msgid ""
"On Linux >= 4.5, the :mod:`fcntl` module exposes the ``FICLONE`` and "
"``FICLONERANGE`` constants, which allow to share some data of one file with "
"another file by reflinking on some filesystems (e.g., btrfs, OCFS2, and "
"XFS). This behavior is commonly referred to as \"copy-on-write\"."
msgstr ""

msgid ""
"On Linux >= 2.6.32, the :mod:`!fcntl` module exposes the ``F_GETOWN_EX``, "
"``F_SETOWN_EX``, ``F_OWNER_TID``, ``F_OWNER_PID``, ``F_OWNER_PGRP`` "
"constants, which allow to direct I/O availability signals to a specific "
"thread, process, or process group. On Linux >= 4.13, the :mod:`!fcntl` "
"module exposes the ``F_GET_RW_HINT``, ``F_SET_RW_HINT``, "
"``F_GET_FILE_RW_HINT``, ``F_SET_FILE_RW_HINT``, and ``RWH_WRITE_LIFE_*`` "
"constants, which allow to inform the kernel about the relative expected "
"lifetime of writes on a given inode or via a particular open file "
"description. On Linux >= 5.1 and NetBSD, the :mod:`!fcntl` module exposes "
"the ``F_SEAL_FUTURE_WRITE`` constant for use with ``F_ADD_SEALS`` and "
"``F_GET_SEALS`` operations. On FreeBSD, the :mod:`!fcntl` module exposes the "
"``F_READAHEAD``, ``F_ISUNIONSTACK``, and ``F_KINFO`` constants. On macOS and "
"FreeBSD, the :mod:`!fcntl` module exposes the ``F_RDAHEAD`` constant. On "
"NetBSD and AIX, the :mod:`!fcntl` module exposes the ``F_CLOSEM`` constant. "
"On NetBSD, the :mod:`!fcntl` module exposes the ``F_MAXFD`` constant. On "
"macOS and NetBSD, the :mod:`!fcntl` module exposes the ``F_GETNOSIGPIPE`` "
"and ``F_SETNOSIGPIPE`` constant."

msgid "The module defines the following functions:"
msgstr ""

msgid ""
"Perform the operation *cmd* on file descriptor *fd* (file objects providing "
"a :meth:`~io.IOBase.fileno` method are accepted as well).  The values used "
"for *cmd* are operating system dependent, and are available as constants in "
"the :mod:`fcntl` module, using the same names as used in the relevant C "
"header files. The argument *arg* can either be an integer value, or a :class:"
"`bytes` object. With an integer value, the return value of this function is "
"the integer return value of the C :c:func:`fcntl` call.  When the argument "
"is bytes it represents a binary structure, e.g. created by :func:`struct."
"pack`. The binary data is copied to a buffer whose address is passed to the "
"C :c:func:`fcntl` call.  The return value after a successful call is the "
"contents of the buffer, converted to a :class:`bytes` object. The length of "
"the returned object will be the same as the length of the *arg* argument. "
"This is limited to 1024 bytes. If the information returned in the buffer by "
"the operating system is larger than 1024 bytes, this is most likely to "
"result in a segmentation violation or a more subtle data corruption."
msgstr ""

msgid "If the :c:func:`fcntl` call fails, an :exc:`OSError` is raised."
msgstr ""

msgid ""
"Raises an :ref:`auditing event <auditing>` ``fcntl.fcntl`` with arguments "
"``fd``, ``cmd``, ``arg``."
msgstr ""

msgid ""
"This function is identical to the :func:`~fcntl.fcntl` function, except that "
"the argument handling is even more complicated."
msgstr ""

msgid ""
"The *request* parameter is limited to values that can fit in 32-bits. "
"Additional constants of interest for use as the *request* argument can be "
"found in the :mod:`termios` module, under the same names as used in the "
"relevant C header files."
msgstr ""

msgid ""
"The parameter *arg* can be one of an integer, an object supporting the read-"
"only buffer interface (like :class:`bytes`) or an object supporting the read-"
"write buffer interface (like :class:`bytearray`)."
msgstr ""

msgid ""
"In all but the last case, behaviour is as for the :func:`~fcntl.fcntl` "
"function."
msgstr ""

msgid ""
"If a mutable buffer is passed, then the behaviour is determined by the value "
"of the *mutate_flag* parameter."
msgstr ""

msgid ""
"If it is false, the buffer's mutability is ignored and behaviour is as for a "
"read-only buffer, except that the 1024 byte limit mentioned above is avoided "
"-- so long as the buffer you pass is at least as long as what the operating "
"system wants to put there, things should work."
msgstr ""

msgid ""
"If *mutate_flag* is true (the default), then the buffer is (in effect) "
"passed to the underlying :func:`ioctl` system call, the latter's return code "
"is passed back to the calling Python, and the buffer's new contents reflect "
"the action of the :func:`ioctl`.  This is a slight simplification, because "
"if the supplied buffer is less than 1024 bytes long it is first copied into "
"a static buffer 1024 bytes long which is then passed to :func:`ioctl` and "
"copied back into the supplied buffer."
msgstr ""

msgid ""
"If the :c:func:`ioctl` call fails, an :exc:`OSError` exception is raised."
