CLUSCTL_NODE_GET_FLAGS control code

Retrieves the flags that are set for a node. Applications use this control code as a ClusterNodeControl parameter.


ClusterNodeControl( 
  hNode,                                             // node handle
  hHostNode,                                         // optional host node
  CLUSCTL_NODE_GET_FLAGS,                            // this control code
  NULL,                                              // input buffer (not used)
  0,                                                 // input buffer size (not used)
  lpOutBuffer,                                       // output buffer: DWORD bitmask
  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 a DWORD bitmask describing flags set for the node. No flags are currently defined for nodes.

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.

System error code

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