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