The RtlIsRoot routine determines whether the specified node is the root node of a splay link tree.
void RtlIsRoot( Links );
Pointer to the node. The node must have been initialized by calling RtlInitializeSplayLinks.
Callers of the Rtl splay link routines are responsible for synchronizing access to the splay link tree. A fast mutex is the most efficient synchronization mechanism to use for this purpose.
Callers of RtlIsRoot must be running at IRQL <= DISPATCH_LEVEL if the splay link tree or just-initialized node at Links is nonpaged. Usually, callers are running at IRQL PASSIVE_LEVEL.
