12 LIRC_SET_REC_CARRIER_RANGE - Set lower bond of the carrier used to modulate
18 .. c:function:: int ioctl( int fd, LIRC_SET_REC_CARRIER_RANGE, __u32 *frequency )
19 :name: LIRC_SET_REC_CARRIER_RANGE
25 File descriptor returned by open().
28 Frequency of the carrier that modulates PWM data, in Hz.
33 This ioctl sets the upper range of carrier frequency that will be recognized
38 To set a range use :ref:`LIRC_SET_REC_CARRIER_RANGE
39 <LIRC_SET_REC_CARRIER_RANGE>` with the lower bound first and later call
40 :ref:`LIRC_SET_REC_CARRIER <LIRC_SET_REC_CARRIER>` with the upper bound.
45 On success 0 is returned, on error -1 and the ``errno`` variable is set
46 appropriately. The generic error codes are described at the
47 :ref:`Generic Error Codes <gen-errors>` chapter.
