#define	SCHEDULER_NODE_OF_WAIT_PRIORITY(node)    RTEMS_CONTAINER_OF( node, Scheduler_Node, Wait.Priority )
#define	SCHEDULER_PRIORITY_MAP(priority)   ( ( priority ) << 1 )
	Maps a priority value to support the append indicator.
#define	SCHEDULER_PRIORITY_UNMAP(priority)   ( ( priority ) >> 1 )
	Returns the plain priority value.
#define	SCHEDULER_PRIORITY_PURIFY(priority)    ( ( priority ) & ~( (Priority_Control) PRIORITY_GROUP_LAST ) )
	Clears the priority append indicator bit.
#define	SCHEDULER_PRIORITY_APPEND(priority)    ( ( priority ) | ( (Priority_Control) PRIORITY_GROUP_LAST ) )
	Returns the priority control with the append indicator bit set.
#define	SCHEDULER_PRIORITY_IS_APPEND(priority)    ( ( ( priority ) & ( (Priority_Control) PRIORITY_GROUP_LAST ) ) != 0 )
	Returns true, if the item should be appended to its priority group, otherwise returns false and the item should be prepended to its priority group.
