5.4.13. ioctl LIRC_SET_TRANSMITTER_MASK¶
LIRC_SET_TRANSMITTER_MASK - Enables send codes on a given set of transmitters
- File descriptor returned by open().
- Mask with channels to enable tx. Channel 0 is the least significant bit.
This ioctl enables the given set of transmitters. The first transmitter is encoded by the least significant bit and so on.
When an invalid bit mask is given, i.e. a bit is set, even though the device does not have so many transitters, then this ioctl returns the number of available transitters and does nothing otherwise.
