12 LIRC_SET_REC_CARRIER - Set carrier used to modulate IR receive.
18 .. cpp:function:: int ioctl( int fd, int request, __u32 *frequency )
24 File descriptor returned by open().
30 Frequency of the carrier that modulates PWM data, in Hz.
35 Set receive carrier used to modulate IR PWM pulses and spaces.
39 If called together with :ref:`LIRC_SET_REC_CARRIER_RANGE`, this ioctl
40 sets the upper bound frequency that will be recognized by the device.
46 On success 0 is returned, on error -1 and the ``errno`` variable is set
47 appropriately. The generic error codes are described at the
