+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.
