Adds a registry tree to the list of registry trees that are replicated for a resource. Applications use this control code as a parameter in the ClusterResourceControl function.

ClusterResourceControl( 
  hResource,                                // resource handle
  hHostNode,                                // optional host node
  CLUSCTL_RESOURCE_ADD_REGISTRY_CHECKPOINT, // this control code
  lpInBuffer,                               // input buffer: string
  cbInBufferSize,                           // input buffer size (bytes)
  NULL,                                     // not used
  0,                                        // not used
  NULL );                                   // not used

Parameters
