Queue

This is a simple stack-like queue system for queuing general data.

---

Creating a new queue

Creating a queue is fairly simple as it just requires one function with no arguments.

Queue* queue = new_queue();

---

Pushing to the queue

Pushing specific data to queue is also fairly simple.

queue_push(queue, (void*) "Hello world");

---

Retrieving the current item from the queue

To get our current item from the queue it will just do queue->current but it also checks if the queue itself exists, if not it will return NULL.

void* current = current_queue(queue)

---

Jumping to the next element

Jumping to the next element involves using the queue_pop function to pop the current item and setting it the next item. This can be done by just simple calling the function

queue_pop(queue)

---

Freeing the queue

Now since the queue is manually allocated you will also need to manually free it. This can be done by using the queue_free method which frees every queue in the given queue.

queue_free(queue)
