CLUSCTL_NETINTERFACE_GET_NODE control code

  • Article

Retrieves the name of the node in which a network interface is installed. Applications use this control code as a ClusterNetInterfaceControl parameter.

ClusterNetInterfaceControl( 
  hNetInterface,                  // network interface handle
  hHostNode,                      // optional host node
  CLUSCTL_NETINTERFACE_GET_NODE,  // 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 parameters are specific to this control code. For complete parameter descriptions, see ClusterNetInterfaceControl.

lpOutBuffer

On a successful return, points to a null-terminated Unicode string containing the name of the network interface.

Return value

ClusterNetInterfaceControl returns one of the following values:

ERROR_SUCCESS

The operation was successful. The lpcbBytesReturned parameter points to the actual size of the returned data.

ERROR_MORE_DATA

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

The operation failed. The value of lpcbBytesReturned is unreliable.

Remarks

The node name is stored in the network interface Node property. To retrieve the Node property along with the other read-only network interface common properties, use the CLUSCTL_NETINTERFACE_GET_RO_COMMON_PROPERTIES control code
