Create a FIFO queue for 1000 packets.
queueObj = wnet.FIFOQueue(MaxSize=1000);
Create a sample packet and specify the packet size.
packet = [255;255]; packetSize = numel(packet);
Add the packet to the tail of the queue.
isQueued = enqueue(queueObj,packet,packetSize);
Get the number of packets in the queue.
numPackets = queueObj.CurrentSize;
Get the number of packet bytes in the queue.
nBytes = queueObj.CurrentSizeBytes;
Check if the queue is full.
status = isFull(queueObj);
Retrieve the first packet from the head of the queue.
PeekedPacket = peek(queueObj);
Remove the packet from the head of the queue.
dequeuedPacket = dequeue(queueObj);
