msgstr ""
#: ../Doc/library/fcntl.rst:14
msgid ""
"This module performs file control and I/O control on file descriptors. It is "
"an interface to the :c:func:`fcntl` and :c:func:`ioctl` Unix routines. For "
"a complete description of these calls, see :manpage:`fcntl(2)` and :manpage:"
"`ioctl(2)` Unix manual pages."
msgstr ""
#: ../Doc/library/fcntl.rst:19
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 a file object, such as ``sys.stdin`` itself, which "
"provides a :meth:`~io.IOBase.fileno` which returns a genuine file descriptor."
msgstr ""
#: ../Doc/library/fcntl.rst:24
msgid "The module defines the following functions:"
msgstr "Le module définit les fonctions suivantes :"
#: ../Doc/library/fcntl.rst:29
msgid ""
"Perform the operation *op* on file descriptor *fd* (file objects providing "
"a :meth:`~io.IOBase.fileno` method are accepted as well). The values used "
"for for *op* 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* is optional, and defaults to the integer "
"value ``0``. When present, it can either be an integer value, or a string. "
"With the argument missing or 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 a string 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 string object. The "
"length of the returned string 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 ""
#: ../Doc/library/fcntl.rst:51

"This function is identical to the :func:`~fcntl.fcntl` function, except that "
"the operations are typically defined in the library module :mod:`termios` "
"and the argument handling is even more complicated."
msgstr ""
#: ../Doc/library/fcntl.rst:55
msgid ""
"The op parameter is limited to values that can fit in 32-bits. Additional "
"constants of interest for use as the *op* argument can be found in the :mod:"
"`termios` module, under the same names as used in the relevant C header "
"files."

"The parameter *arg* can be one of an integer, absent (treated identically to "
"the integer ``0``), an object supporting the read-only buffer interface "
"(most likely a plain Python string) or an object supporting the read-write "
"buffer interface."

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

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 as least as long as what the operating "
"system wants to put there, things should work."
msgstr ""
#: ../Doc/library/fcntl.rst:75
msgid ""
"If *mutate_flag* is true, 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 ""
#: ../Doc/library/fcntl.rst:83
msgid ""
"If *mutate_flag* is not supplied, then from Python 2.5 it defaults to true, "
"which is a change from versions 2.3 and 2.4. Supply the argument explicitly "
"if version portability is a priority."
