Assigns the resource-management priority for this resource.
DWORD SetPriority( DWORD PriorityNew );
Returns the previous priority value for the resource.
SetPriority is used for priority control of managed resources. This method returns 0 on non-managed resources.
Priorities are used to determine when managed resources are to be removed from memory. A resource assigned a low priority is removed before a resource with a high priority. If two resources have the same priority, the resource that was used more recently is kept in memory; the other resource is removed. Managed resources have a default priority of 0.
