CLUSCTL_NODE_ENUM_PRIVATE_PROPERTIES control code
Retrieves a list of node private property names. Applications use this control code as a ClusterNodeControl parameter.
ClusterNodeControl(
hNode, // node handle
hHostNode, // optional host node
CLUSCTL_NODE_ENUM_PRIVATE_PROPERTIES, // this control code
NULL, // input buffer (not used)
0, // input buffer size (not used)
lpOutBuffer, // output buffer: array of strings
cbOutBufferSize, // allocated buffer size (bytes)
lpcbBytesReturned ); // actual size of resulting data (bytes)
Parameters
The following control code function parameter is specific to this control code. For complete parameter descriptions, see ClusterNodeControl.
-
lpOutBuffer
-
On a successful return, contains an array of null-terminated Unicode strings with an additional NULL terminator appended to the last string. Each string in the array contains the name of a read/write node private property.
Return value
ClusterNodeControl 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.
Remarks
By default, failover clusters do not define any private properties for nodes.
