Data Structures
struct	ThreadsQueue
	Generic threads bidirectional linked list header and element. More...
struct	ThreadsList
	Generic threads single link list, it works like a stack. More...
Defines
#define	queue_init(tqp)   ((tqp)->p_next = (tqp)->p_prev = (Thread *)(tqp));
	Threads queue initialization.
#define	list_init(tlp)   ((tlp)->p_next = (Thread *)(tlp))
	Threads list initialization.
#define	isempty(p)   ((p)->p_next == (Thread *)(p))
	Evaluates to TRUE if the specified threads queue or list is empty.
#define	notempty(p)   ((p)->p_next != (Thread *)(p))
	Evaluates to TRUE if the specified threads queue or list is not empty.
#define	_THREADSQUEUE_DATA(name)   {(Thread *)&name, (Thread *)&name}
	Data part of a static threads queue initializer.
#define	THREADSQUEUE_DECL(name)   ThreadsQueue name = _THREADSQUEUE_DATA(name)
	Static threads queue initializer.
