ioctl LIRC_SET_WIDEBAND_RECEIVER

Name

Synopsis

.. c:macro:: LIRC_SET_WIDEBAND_RECEIVER

int ioctl(int fd, LIRC_SET_WIDEBAND_RECEIVER, __u32 *enable)

Arguments

fd File descriptor returned by open().

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 implicitly 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.
