[][src]Function openthread_sys::otChildSupervisionGetInterval

pub unsafe extern "C" fn otChildSupervisionGetInterval(
    aInstance: *mut otInstance
) -> u16

Get the child supervision interval (in seconds).

Child supervision feature provides a mechanism for parent to ensure that a message is sent to each sleepy child within the supervision interval. If there is no transmission to the child within the supervision interval, OpenThread enqueues and sends a supervision message (a data message with empty payload) to the child.

@param[in] aInstance A pointer to an OpenThread instance.

@returns The child supervision interval. Zero indicates that child supervision is disabled.
