***********************
ioctl LIRC_GET_FEATURES
***********************
Name
====
LIRC_GET_FEATURES - Get the underlying hardware device's features
Synopsis
========
.. c:function:: int ioctl( int fd, LIRC_GET_FEATURES, __u32 *features)
:name: LIRC_GET_FEATURES
Arguments
=========
``fd``
File descriptor returned by open().
``features``
Bitmask with the LIRC features.
Description
===========
Get the underlying hardware device's features. If a driver does not
announce support of certain features, calling of the corresponding ioctls
is undefined.
LIRC features
=============
.. _LIRC-CAN-REC-RAW:
``LIRC_CAN_REC_RAW``
Unused. Kept just to avoid breaking uAPI.
.. _LIRC-CAN-REC-PULSE:
``LIRC_CAN_REC_PULSE``
Unused. Kept just to avoid breaking uAPI.
:ref:`LIRC_MODE_PULSE <lirc-mode-pulse>` can only be used for transmitting.
.. _LIRC-CAN-REC-MODE2:
``LIRC_CAN_REC_MODE2``
The driver is capable of receiving using
:ref:`LIRC_MODE_MODE2 <lirc-mode-MODE2>`.
.. _LIRC-CAN-REC-LIRCCODE:
``LIRC_CAN_REC_LIRCCODE``
Unused. Kept just to avoid breaking uAPI.
.. _LIRC-CAN-REC-SCANCODE:
``LIRC_CAN_REC_SCANCODE``
The driver is capable of receiving using
:ref:`LIRC_MODE_SCANCODE <lirc-mode-SCANCODE>`.
.. _LIRC-CAN-SET-SEND-CARRIER:
``LIRC_CAN_SET_SEND_CARRIER``
The driver supports changing the modulation frequency via
:ref:`ioctl LIRC_SET_SEND_CARRIER <LIRC_SET_SEND_CARRIER>`.
.. _LIRC-CAN-SET-SEND-DUTY-CYCLE:
``LIRC_CAN_SET_SEND_DUTY_CYCLE``
The driver supports changing the duty cycle using
:ref:`ioctl LIRC_SET_SEND_DUTY_CYCLE <LIRC_SET_SEND_DUTY_CYCLE>`.
.. _LIRC-CAN-SET-TRANSMITTER-MASK:
``LIRC_CAN_SET_TRANSMITTER_MASK``
The driver supports changing the active transmitter(s) using
:ref:`ioctl LIRC_SET_TRANSMITTER_MASK <LIRC_SET_TRANSMITTER_MASK>`.
.. _LIRC-CAN-SET-REC-CARRIER:
``LIRC_CAN_SET_REC_CARRIER``
The driver supports setting the receive carrier frequency using
:ref:`ioctl LIRC_SET_REC_CARRIER <LIRC_SET_REC_CARRIER>`.
.. _LIRC-CAN-SET-REC-DUTY-CYCLE-RANGE:
``LIRC_CAN_SET_REC_DUTY_CYCLE_RANGE``
Unused. Kept just to avoid breaking uAPI.
.. _LIRC-CAN-SET-REC-CARRIER-RANGE:
``LIRC_CAN_SET_REC_CARRIER_RANGE``
The driver supports
:ref:`ioctl LIRC_SET_REC_CARRIER_RANGE <LIRC_SET_REC_CARRIER_RANGE>`.
.. _LIRC-CAN-GET-REC-RESOLUTION:
``LIRC_CAN_GET_REC_RESOLUTION``
The driver supports
:ref:`ioctl LIRC_GET_REC_RESOLUTION <LIRC_GET_REC_RESOLUTION>`.
.. _LIRC-CAN-SET-REC-TIMEOUT:
``LIRC_CAN_SET_REC_TIMEOUT``
The driver supports
:ref:`ioctl LIRC_SET_REC_TIMEOUT <LIRC_SET_REC_TIMEOUT>`.
.. _LIRC-CAN-SET-REC-FILTER:
``LIRC_CAN_SET_REC_FILTER``
Unused. Kept just to avoid breaking uAPI.
.. _LIRC-CAN-MEASURE-CARRIER:
``LIRC_CAN_MEASURE_CARRIER``
The driver supports measuring of the modulation frequency using
:ref:`ioctl LIRC_SET_MEASURE_CARRIER_MODE <LIRC_SET_MEASURE_CARRIER_MODE>`.
.. _LIRC-CAN-USE-WIDEBAND-RECEIVER:
``LIRC_CAN_USE_WIDEBAND_RECEIVER``
The driver supports learning mode using
:ref:`ioctl LIRC_SET_WIDEBAND_RECEIVER <LIRC_SET_WIDEBAND_RECEIVER>`.
.. _LIRC-CAN-NOTIFY-DECODE:
``LIRC_CAN_NOTIFY_DECODE``
Unused. Kept just to avoid breaking uAPI.
.. _LIRC-CAN-SEND-RAW:
``LIRC_CAN_SEND_RAW``
Unused. Kept just to avoid breaking uAPI.
.. _LIRC-CAN-SEND-PULSE:
``LIRC_CAN_SEND_PULSE``
The driver supports sending (also called as IR blasting or IR TX) using
:ref:`LIRC_MODE_PULSE <lirc-mode-pulse>`.
.. _LIRC-CAN-SEND-MODE2:
``LIRC_CAN_SEND_MODE2``
Unused. Kept just to avoid breaking uAPI.
:ref:`LIRC_MODE_MODE2 <lirc-mode-mode2>` can only be used for receiving.
.. _LIRC-CAN-SEND-LIRCCODE:
``LIRC_CAN_SEND_LIRCCODE``
Unused. Kept just to avoid breaking uAPI.
.. _LIRC-CAN-SEND-SCANCODE:
``LIRC_CAN_SEND_SCANCODE``
The driver supports sending (also called as IR blasting or IR TX) using
:ref:`LIRC_MODE_SCANCODE <lirc-mode-SCANCODE>`.
Return Value
============
On success 0 is returned, on error -1 and the ``errno`` variable is set
appropriately. The generic error codes are described at the
:ref:`Generic Error Codes <gen-errors>` chapter.
