Arduino-Queue

A queue for Arduino implemented in C based on a circular array. This is a queue for bytes, but could be easily modified to handle other datatypes.

Usage

Since this queue is implemented in C and not C++, using it is slightly different for people who are used to more "standard" arduino libraries.

To use it, first #include "Queue.h

Then, allocate a queue and initialize it

Queue *q = (Queue *)malloc(sizeof(Queue)); 
alloc(q, 20);

You now have a Queue named q of size 20 ready to go.

To enqueue a byte, simply call enqueue() on your queue and byte

for (int i=0; i<20; i++) {
	enqueue(q, i);
}  

To dequeue bytes, call dequeue() on the queue. For example

while(q->size > 0) {
	b = dequeue(q);
	Serial.println(b);
}

will remove everything off the queue and print it.

When you're done with the queue, call cleanup(q).
