There are lots of tables that are not properly displayed in LaTeX/PDF. Fix the tablecolumns, add longtable where needed and LaTeX formatting macros, in order to address such issues. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

CEC_ADAP_G_CONNECTOR_INFO - Query HDMI connector information

|

Synopsis

|
========
|
|
|
|
.. c:macro:: CEC_ADAP_G_CONNECTOR_INFO
|
|
|
|
``int ioctl(int fd, CEC_ADAP_G_CONNECTOR_INFO, struct cec_connector_info *argp)``
|
|
|
|
Arguments
|
|
=========
|
|
|
|
``fd``
|
|
File descriptor returned by :c:func:`open()`.
|
|
|
|
``argp``
|
|
|
|
Description
|
|
===========
|
|
|
|
Using this ioctl an application can learn which HDMI connector this CEC
|
|
device corresponds to. While calling this ioctl the application should
|
|
provide a pointer to a cec_connector_info struct which will be populated
|
|
by the kernel with the info provided by the adapter's driver. This ioctl
|
|
is only available if the ``CEC_CAP_CONNECTOR_INFO`` capability is set.
