Description

===========

To query the current CEC logical addresses, applications call

:ref:`ioctl CEC_ADAP_G_LOG_ADDRS <CEC_ADAP_G_LOG_ADDRS>` with a pointer to a

:c:type:`struct cec_log_addrs` where the driver stores the logical addresses.

struct :c:type:`cec_log_addrs` where the driver stores the logical addresses.

To set new logical addresses, applications fill in

:c:type:`struct cec_log_addrs` and call :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`

struct :c:type:`cec_log_addrs` and call :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`

with a pointer to this struct. The :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`

is only available if ``CEC_CAP_LOG_ADDRS`` is set (the ``ENOTTY`` error code is

returned otherwise). The :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`

Attempting to call :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>` when

logical address types are already defined will return with error ``EBUSY``.

To receive a CEC message the application has to fill in the

``timeout`` field of :c:type:`struct cec_msg` and pass it to :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.

:ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.

If the file descriptor is in non-blocking mode and there are no received

messages pending, then it will return -1 and set errno to the ``EAGAIN``

error code. If the file descriptor is in blocking mode and ``timeout``

   be non-zero).

To send a CEC message the application has to fill in the

To send a CEC message the application has to fill in the struct

:c:type:` cec_msg` and pass it to :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`.

The :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` is only available if

``CEC_CAP_TRANSMIT`` is set. If there is no more room in the transmit

queue, then it will return -1 and set errno to the ``EBUSY`` error code.

The transmit queue has enough room for 18 messages (about 1 second worth
