[−][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.
