nrf_802154_queue_push_begin()

void * nrf_802154_queue_push_begin

(

const nrf_802154_queue_t *

p_queue

)

Returns pointer to the next item to be written to the queue.

This function is to be used when writing data to the queue directly (no copy). Returned pointer is valid when the queue is not full (nrf_802154_queue_is_full returned false). To write an item to the queue perform following.

if (!nrf_802154_queue_is_full(&queue))
{
    my_item_t * p_item = (my_item_t *)nrf_802154_queue_push_begin(&queue);
    ... p_item is now direct pointer into memory of the queue, fill all data at p_item pointer
    p_item->some_field = some_value;
    ... fill all data at p_item pointer
    nrf_802154_queue_push_commit(&queue)
}

To ensure thread-safety external locking is required.

Parameters

[in]

p_queue

Pointer to the queue instance.

Returns

Pointer to the next item to be written.
