The c language parser checks if there are duplicated object definitions. That causes lots of warnings like: WARNING: duplicate C object description of ioctl Let's remove those by telling Sphinx that the language for those objects are c++. The look of the descriptions will be close, and the warnings will be gone. Please notice that we had to keep a few of them as C, as the c++ parser seems to be broken when it finds an enum. Yet, this reduced from 219 warnings to 143, with is a good thing. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

Synopsis

========
|
|
|
|
.. cpp:function:: int ioctl( int fd, int request )
|
|
|
|
Description
|
|
===========
|
|
|
|
As the video/audio devices become more complicated it becomes harder to
|
|
debug problems. When this ioctl is called the driver will output the
|
|
current device status to the kernel log. This is particular useful when
|
|
dealing with problems like no sound, no video and incorrectly tuned
|
|
channels. Also many modern devices autodetect video and audio standards
|
|
and this ioctl will report what the device thinks what the standard is.
|
|
Mismatches may give an indication where the problem is.
|
|
|
|
This ioctl is optional and not all drivers support it. It was introduced
|
|
in Linux 2.6.15.
|
|
|
|
|
|
Return Value
|
|
============
|
|
|
|
On success 0 is returned, on error -1 and the ``errno`` variable is set
|
|
appropriately. The generic error codes are described at the
|
|
:ref:`Generic Error Codes <gen-errors>` chapter.
