the C domain
|

------------
|
||||
|
||||
The `Sphinx C Domain`_ (name c) is suited for documentation of C API. E.g. a
|
||||
function prototype:
|
||||
|
||||
.. code-block:: rst
|
||||
|
||||
.. c:function:: int ioctl( int fd, int request )
|
||||
|
||||
The C domain of the kernel-doc has some additional features. E.g. you can
|
||||
*rename* the reference name of a function with a common name like ``open`` or
|
||||
``ioctl``:
|
||||
|
||||
.. code-block:: rst
|
||||
|
||||
.. c:function:: int ioctl( int fd, int request )
|
||||
:name: VIDIOC_LOG_STATUS
|
||||
|
||||
The func-name (e.g. ioctl) remains in the output but the ref-name changed from
|
||||
``ioctl`` to ``VIDIOC_LOG_STATUS``. The index entry for this function is also
|
||||
changed to ``VIDIOC_LOG_STATUS`` and the function can now referenced by:
|
||||
|
||||
.. code-block:: rst
|
||||

:c:func:`VIDIOC_LOG_STATUS`

List of customizations:
|
||||
|
||||
* Moved the *duplicate C object description* warnings for function
|
||||
declarations in the nitpicky mode. See Sphinx documentation for
|
||||
the config values for ``nitpick`` and ``nitpick_ignore``.
|
||||
|
||||
* Add option 'name' to the "c:function:" directive. With option 'name' the
|
||||
ref-name of a function can be modified. E.g.::
|
||||
|
||||
.. c:function:: int ioctl( int fd, int request )
|
||||
:name: VIDIOC_LOG_STATUS
|
||||
|
||||
The func-name (e.g. ioctl) remains in the output but the ref-name changed
|
||||
from 'ioctl' to 'VIDIOC_LOG_STATUS'. The function is referenced by::
|
||||
|
||||
* :c:func:`VIDIOC_LOG_STATUS` or
|
||||
* :any:`VIDIOC_LOG_STATUS` (``:any:`` needs sphinx 1.3)
