Confirms whether the security principal of the designated resource can be managed by the cluster. Applications use this control code as a parameter to the ClusterResourceControl function.

ClusterResourceControl( hResource,                             // resource handle
                        NULL,                                  // optional node handle (not used)
                        CLUSCTL_RESOURCE_NETNAME_VALIDATE_VCO, // control code
                        lpInBuffer,                            // input buffer: security principal name
                        nInBufferSize,                         // input buffer size
                        NULL,                                  // output buffer (not used)
                        0,                                     // output buffer size (not used)
                        NULL );                                // returned data size (not used)
