CLUSCTL_NETINTERFACE_GET_NETWORK control code

  • Article

Retrieves the name of the network to which a network interface is connected. Applications use this control code as a ClusterNetInterfaceControl parameter.

ClusterNetInterfaceControl( 
  hNetInterface,                     // network interface handle
  hHostNode,                         // optional host node
  CLUSCTL_NETINTERFACE_GET_NETWORK,  // this control code
  NULL,                              // input buffer (not used)
  0,                                 // input buffer size (not used)
  lpOutBuffer,                       // output buffer: string
  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 null-terminated Unicode string containing the name of the network interface.

Return value

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

Remarks

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