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