uint32_t mac_ready_to_sleep

(

void

)

Checks if the mac stack is ready to sleep.

Checks if the mac stack is in inactive state for beacon support

or idle in case of no beacon support.

Returns

32bit time duration in microseconds for which the mac is ready to sleep

For No beacon support 1 if stack is idle,0 if it is busy

bool mac_task

(

void

)

Runs the MAC scheduler.

This function runs the MAC scheduler.

MLME and MCPS queues are removed alternately, starting with MLME queue.

Returns

true if event is dispatched, false if no event to dispatch.
