5.4.8. ioctls LIRC_GET_MIN_TIMEOUT and LIRC_GET_MAX_TIMEOUT¶
LIRC_GET_MIN_TIMEOUT / LIRC_GET_MAX_TIMEOUT - Obtain the possible timeout range for IR receive.
ioctl(int fd, LIRC_GET_MIN_TIMEOUT, __u32 *timeout)¶
ioctl(int fd, LIRC_GET_MAX_TIMEOUT, __u32 *timeout)¶
- File descriptor returned by open().
- Timeout, in microseconds.
Some devices have internal timers that can be used to detect when there’s no IR activity for a long time. This can help lircd in detecting that a IR signal is finished and can speed up the decoding process. Returns an integer value with the minimum/maximum timeout that can be set.
Some devices have a fixed timeout, in that case both ioctls will return the same value even though the timeout cannot be changed via ioctl LIRC_GET_REC_TIMEOUT and LIRC_SET_REC_TIMEOUT.
