41 .. _LIRC-CAN-REC-RAW:
47 .. _LIRC-CAN-REC-PULSE:
52     :ref:`LIRC_MODE_PULSE <lirc-mode-pulse>` can only be used for transmitting.
54 .. _LIRC-CAN-REC-MODE2:
59     :ref:`LIRC_MODE_MODE2 <lirc-mode-MODE2>` is used. This also implies
60     that :ref:`LIRC_MODE_SCANCODE <lirc-mode-SCANCODE>` is also supported,
62     :ref:`lirc_set_rec_mode` to switch modes.
64 .. _LIRC-CAN-REC-LIRCCODE:
70 .. _LIRC-CAN-REC-SCANCODE:
75     :ref:`LIRC_MODE_SCANCODE <lirc-mode-SCANCODE>` is used.
77 .. _LIRC-CAN-SET-SEND-CARRIER:
81     The driver supports changing the modulation frequency via
84 .. _LIRC-CAN-SET-SEND-DUTY-CYCLE:
91 .. _LIRC-CAN-SET-TRANSMITTER-MASK:
98 .. _LIRC-CAN-SET-REC-CARRIER:
102     The driver supports setting the receive carrier frequency using
105 .. _LIRC-CAN-SET-REC-CARRIER-RANGE:
112 .. _LIRC-CAN-GET-REC-RESOLUTION:
119 .. _LIRC-CAN-SET-REC-TIMEOUT:
126 .. _LIRC-CAN-MEASURE-CARRIER:
130     The driver supports measuring of the modulation frequency using
133 .. _LIRC-CAN-USE-WIDEBAND-RECEIVER:
137     The driver supports learning mode using
140 .. _LIRC-CAN-SEND-RAW:
146 .. _LIRC-CAN-SEND-PULSE:
151     :ref:`LIRC_MODE_PULSE <lirc-mode-pulse>`. This implies that
152     :ref:`LIRC_MODE_SCANCODE <lirc-mode-SCANCODE>` is also supported for
154     :ref:`lirc_set_send_mode` to switch modes.
156 .. _LIRC-CAN-SEND-MODE2:
161     :ref:`LIRC_MODE_MODE2 <lirc-mode-mode2>` can only be used for receiving.
163 .. _LIRC-CAN-SEND-LIRCCODE:
172 On success 0 is returned, on error -1 and the ``errno`` variable is set
