+
+LIRC_SET_WIDEBAND_RECEIVER - enable wide band receiver.
+
+Synopsis
+========
+
+.. cpp:function:: int ioctl( int fd, int request, __u32 *enable )
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by open().
+
+``request``
+    LIRC_SET_WIDEBAND_RECEIVER
+
+``enable``
+    enable = 1 means enable wideband receiver, enable = 0 means disable
+    wideband receiver.
+
+
+Description
+===========
+
+Some receivers are equipped with special wide band receiver which is
+intended to be used to learn output of existing remote. This ioctl
+allows enabling or disabling it.
+
+This might be useful of receivers that have otherwise narrow band receiver
+that prevents them to be used with some remotes. Wide band receiver might
+also be more precise. On the other hand its disadvantage it usually
+reduced range of reception.
+
+.. note:: Wide band receiver might be implictly enabled if you enable
+    carrier reports. In that case it will be disabled as soon as you disable
+    carrier reports. Trying to disable wide band receiver while carrier
+    reports are active will do nothing.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
