ioctl CEC_ADAP_G_CONNECTOR_INFO
*******************************

Name
====

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.
