CLUSCTL_CLUSTER_GET_FQDN control code

Retrieves the fully qualified domain name (FQDN) of a cluster. Applications use this control code as a ClusterControl parameter.

ClusterControl( 
  hCluster,                               // cluster handle
  hHostNode,                              // optional node handle
  CLUSCTL_CLUSTER_GET_FQDN,               // this control code
  NULL,                                   // input buffer (not used)
  0,                                      // input buffer size (not used)
  lpOutBuffer,                            // output buffer: string
  cbOutBufferSize,                        // output buffer size (bytes)
  lpcbBytesReturned                       // resulting data size (bytes)
);

Parameters

The following control code function parameter is specific to this control code. For complete parameter descriptions, see ClusterControl.

lpOutBuffer

On a successful return, points to a null-terminated Unicode string specifying the FQDN of the cluster.

Return value

ClusterControl returns one of the following values.

ERROR_SUCCESS

0

The operation completed successfully. The lpcbBytesReturned parameter points to the actual size of the returned data.

ERROR_MORE_DATA

234 (0xEA)

More data is available. The output buffer pointed to by lpOutBuffer was not large enough to hold the data resulting from the operation. The lpcbBytesReturned parameter points to the size required for the output buffer.

System error code

If any other value is returned, then the operation failed. The value of lpcbBytesReturned is unreliable.
