CLUSCTL_GROUP_GET_COMMON_PROPERTIES control code

Retrieves the read/write group common properties for a group. Applications use this control code as a ClusterGroupControl parameter.

ClusterGroupControl( 
  hGroup,                               // group handle
  hHostNode,                            // optional node handle
  CLUSCTL_GROUP_GET_COMMON_PROPERTIES,  // this control code
  NULL,                                 // input buffer (not used)
  0,                                    // input buffer size (not used)
  lpOutBuffer,                          // output buffer: property list
  cbOutBufferSize,                      // output buffer size (bytes)
  lpcbBytesReturned                     // resulting data size (bytes)
);

Parameters

The following control code function parameters are specific to this control code. For complete parameter descriptions, see ClusterGroupControl.

lpOutBuffer

On a successful return, points to a property list containing the specified group's read/write group common properties.

Return value

ClusterGroupControl 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

For information on working with property lists, see Using Property Lists.

Do not use any group control codes in any resource DLL entry point function. Group control codes can safely be called from a worker thread. For more information, see Function Calls to Avoid in Resource DLLs.
