The RtlIsLeftChild routine determines whether a given splay link is the left child of a node in a splay link tree.
void RtlIsLeftChild( Links );
Pointer to the node. The node must have been initialized by calling RtlInitializeSplayLinks.
The given node at Links must have a parent node in the tree. A caller can determine whether this node has a parent with RtlIsRoot. If RtlIsRoot returns FALSE, Links is a valid parameter to RtlIsLeftChild.
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 RtlIsLeftChild can be running at IRQL <= DISPATCH_LEVEL if the splay link tree is nonpaged. Usually, callers are running at IRQL PASSIVE_LEVEL.
