Modifies an existing file share on a physical disk resource. Applications use this control code as a parameter to the ClusterResourceControl function.

ClusterResourceControl( hResource,                                // cluster handle
                        hHostNode,                                // optional node handle
                        CLUSCTL_RESOURCE_FILESERVER_SHARE_MODIFY, // this control code
                        lpInBuffer,                               // input buffer: property list
                        nInBufferSize,                            // input buffer size
                        lpOutBuffer,                              // output buffer (not used)
                        cbOutBufferSize,                          // output buffer size (not used)
                        lpcbBytesReturned );                      // returned data size (not used)
