CLUSCTL_NODE_UNKNOWN control code

This control code verifies that control codes are being processed on the node where execution of the control is directed. Applications use this control code as a ClusterNodeControl parameter.


ClusterNodeControl( 
  hNode,                                             // node handle
  hHostNode,                                         // optional host node
  CLUSCTL_NODE_UNKNOWN,                              // this control code
  NULL,                                              // input buffer (not used)
  0,                                                 // input buffer size (not used)
  NULL,                                              // output buffer (not used)
  0,                                                 // output buffer size (not used)
  NULL );                                            // actual size of resulting data (not used)
