RESOURCE.SYS provides two IOCtls that allow a ring 3 application to obtain a "snapshot" of the Resource Management data structures. Obtaining a snapshot of the Resource Management data structures consists of the following two steps:

• A data structure representing a depth-first traversal of the Resource Manager node structure is obtained.

• For each node traversed, the following information is provided:

  A Resource Manager handle to access the node.
  The depth of the node in the tree structure.

  3.
  A copy of each Resource Manager node can be obtained by supplying the node handle returned in Step 1.
