CLUSCTL_CLUSTER_GET_CLUSDB_TIMESTAMP control code

Retrieves a cluster database timestamp for a cluster. Applications use this control code as a ClusterControl parameter.

ClusterControl( 
  hCluster,                                 // cluster handle
  hHostNode,                                // optional node handle
  CLUSCTL_CLUSTER_GET_CLUSDB_TIMESTAMP,     // this control code
  lpInBuffer,                               // input buffer
  nInBufferSize,                            // input buffer size
  lpOutBuffer,                              // output buffer: array of strings
  nOutBufferSize,                           // output buffer size
  lpBytesReturned                           // resulting data size
);

Parameters

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

hCluster [in]

A handle to the cluster that is identified in the cluster database timestamp.

hHostNode [in, optional]

A handle to the node that is to perform the operation. If NULL, the local node performs the operation.

lpInBuffer [in, optional]

A pointer to the input buffer that contains the data for the operation, or NULL if no information is needed.

nInBufferSize [in]

The allocated size of of the lpInBuffer parameter, in bytes.

lpOutBuffer [out, optional]

A pointer to the output buffer that receives the data retrieved by the operation, or NULL if no data will is retrieved.

nOutBufferSize [in]

The allocated size of of the lpOutBuffer parameter, in bytes.

lpBytesReturned [out, optional]

The actual size of the data retrieved by the operation, in bytes.

Return value

When an application uses CLUSCTL_CLUSTER_GET_CLUSDB_TIMESTAMP as a parameter for ClusterControl, ClusterControl returns one of the following values:

ERROR_SUCCESS

0

The operation completed successfully. This value is returned if the lpBytesReturned parameter points to the actual size of the returned data.

ERROR_MORE_DATA

234 (0xEA)

More data is available. This value is returned if the buffer for lpOutBuffer was not large enough to hold the data that was returned by the operation.

System error code

The operation was not successful. If the operation required an output buffer, the value specified by lpBytesReturned (if not NULL on input) is unreliable.
