18 .. cpp:function:: int ioctl( int fd, int request, __u32 *frequency )
24 File descriptor returned by open().
27 LIRC_SET_REC_CARRIER_RANGE
30 Frequency of the carrier that modulates PWM data, in Hz.
35 This ioctl sets the upper range of carrier frequency that will be recognized
40 To set a range use :ref:`LIRC_SET_REC_CARRIER_RANGE
41 <LIRC_SET_REC_CARRIER_RANGE>` with the lower bound first and later call
42 :ref:`LIRC_SET_REC_CARRIER <LIRC_SET_REC_CARRIER>` with the upper bound.
47 On success 0 is returned, on error -1 and the ``errno`` variable is set
48 appropriately. The generic error codes are described at the
49 :ref:`Generic Error Codes <gen-errors>` chapter.
