RtlRealSuccessor function

Description

The RtlRealSuccessor routine returns a pointer to the successor of the specified node in the splay link tree.

Parameters

Pointer to the node. The node must have been initialized by calling RtlInitializeSplayLinks.

Return value

RtlRealSuccessor returns a pointer to the successor of the node at Links, or NULL if the node has no successor.

Remarks

The real successor of a given node is determined as follows:

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 RtlRealSuccessor must be running at IRQL <= DISPATCH_LEVEL if the tree is nonpaged. Usually, callers are running at IRQL PASSIVE_LEVEL.
