Description

This are the functions to use when working with any queue of processes in the CPU.

Details

proc_queue_t

DECLARE_PROC_QUEUE()

#define     DECLARE_PROC_QUEUE(queue)

Declares a new and empty process queue with name queue.

queue : name for the queue.

proc_queue_empty()

#define     proc_queue_empty(queue)

Is queue empty?

queue : process queue involved.

proc_data()

#define     proc_data(element)

Retrives the process data from the queue element.

element : process queue element involved.

proc_queue_next()

#define     proc_queue_next(element)

Gets the next element on the queue starting at element.

element : process queue element involved.

proc_queue_find()

#define     proc_queue_find(queue, proc)

Find the queue element for process proc.

queue : process queue involved.
proc : process involved.

proc_queue_len()

#define     proc_queue_len(queue)

Calculate the number of elements on queue.

queue : process queue involved.

proc_queue_init()

#define     proc_queue_init(queue)

Initializes process queue queue.

Note: applyed to a non empty queue will loose all its elements.

queue : process queue involved.

proc_queue_foreach()

#define     proc_queue_foreach(queue, func, data)

Will call func for every process on queue using the process pointer as the first arguemt and data as the second.

queue : process queue involved.
func : function to be called.
data : second argument to func.

proc_queue_concat()

#define     proc_queue_concat(dest, orig1, orig2)

Concatenates orig1 and orig2 into dest.

dest : Target queue.
orig1 : First source queue.
orig2 : Second source queue.

proc_queue_remove()

#define     proc_queue_remove(queue, proc)

Remove proc from queue.

queue : process queue involved.
proc : process to be removed.

proc_queue_append()

#define     proc_queue_append(queue, proc)

Append proc to queue.

queue : process queue involved.
proc : process to be appended.

proc_queue_nth()

#define     proc_queue_nth(queue, n)

Get element number n from queue.

queue : queue involved.
n : element index.

proc_queue_end()

#define proc_queue_end(element) proc_queue_empty(element)

Is this element the end of the queue?

element : process queue element involved.
