^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) ``fd``
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27)     File descriptor returned by open().
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) ``duty_cycle``
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30)     Duty cicle, describing the pulse width in percent (from 1 to 99) of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31)     the total cycle. Values 0 and 100 are reserved.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) Description
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34) ===========
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36) Get/set the duty cycle of the carrier signal for IR transmit.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38) Currently, no special meaning is defined for 0 or 100, but this
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39) could be used to switch off carrier generation in the future, so
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40) these values should be reserved.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 43) ============
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 44) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 45) On success 0 is returned, on error -1 and the ``errno`` variable is set
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 46) appropriately. The generic error codes are described at the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 47) :ref:`Generic Error Codes <gen-errors>` chapter.
