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.
