36 Some receivers are equipped with special wide band receiver which is
37 intended to be used to learn output of existing remote. This ioctl
38 allows enabling or disabling it.
40 This might be useful of receivers that have otherwise narrow band receiver
41 that prevents them to be used with some remotes. Wide band receiver might
42 also be more precise. On the other hand its disadvantage it usually
43 reduced range of reception.
45 .. note:: Wide band receiver might be implictly enabled if you enable
46 carrier reports. In that case it will be disabled as soon as you disable
47 carrier reports. Trying to disable wide band receiver while carrier
48 reports are active will do nothing.
54 On success 0 is returned, on error -1 and the ``errno`` variable is set
55 appropriately. The generic error codes are described at the
56 :ref:`Generic Error Codes <gen-errors>` chapter.
