CLUSCTL_RESOURCE_GET_DNS_NAME control code
Retrieves the DNS name of the designated resource. Applications use this control code as a parameter to the ClusterResourceControl function.
ClusterResourceControl( hResource, // resource handle
hHostNode, // optional node handle
CLUSCTL_RESOURCE_GET_DNS_NAME, // this control code
NULL, // input buffer (not used)
0, // input buffer size (not used)
lpOutBuffer, // output buffer DNS name
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 ClusterResourceControl.
-
lpOutBuffer
-
On a successful return, points to a null-terminated unicode string containing the DNS name of a designated resource.
Return value
ClusterResourceControl 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.
