CLUSCTL_RESOURCE_TYPE_STORAGE_IS_CSV_FILE control code

Queries whether a file is stored on a cluster shared volume (CSV) that is accessible to all nodes in the cluster. Applications use this control code as a parameter to the ClusterResourceTypeControl function, and resource DLLs receive the control code as a parameter to the ResourceTypeControl callback function.

ClusterResourceTypeControl( hCluster,                                  // cluster handle
                            lpszResTypeName,                           // resource type name
                            hHostNode,                                 // optional host node
                            CLUSCTL_RESOURCE_TYPE_STORAGE_IS_CSV_FILE, // this control code
                            lpInBuffer,                                // input buffer: path to file
                            cbInBufferSize,                            // input buffer size
                            NULL,                                      // lpOutBuffer not used
                            0,                                         // cbOutBufferSize not used
                            NULL );                                    // lpcbBytesReturned not used
