CLUSCTL_NETINTERFACE_GET_RO_PRIVATE_PROPERTIES control code

Retrieves the read-only private properties for a network interface. Applications use this control code as a ClusterNetInterfaceControl parameter.

ClusterNetInterfaceControl( 
  hNetInterface,                                   // network interface handle
  hHostNode,                                       // optional host node
  CLUSCTL_NETINTERFACE_GET_RO_PRIVATE_PROPERTIES,  // this control code
  NULL,                                            // input buffer (not used)
  0,                                               // input buffer size (not used)
  lpOutBuffer,                                     // output buffer: property list
  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 ClusterNetInterfaceControl.

lpOutBuffer

On a successful return, points to a property list containing the specified network interface's read-only private properties.

Return value

ClusterNetInterfaceControl returns one of the following values.

ERROR_SUCCESS

0

The operation was successful. 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 value is returned, then the operation failed. The value of lpcbBytesReturned is unreliable.

Remarks

By default, failover clusters do not define private properties for network interfaces.
