CLUSCTL_GROUP_SET_PRIVATE_PROPERTIES control code

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

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

Parameters

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

lpInBuffer

Pass a pointer to a property list containing one or more read/write group private properties. Properties that do not already exist will be created.

Return value

ClusterGroupControl returns one of the following values.

ERROR_SUCCESS

0

The operation completed successfully. The property list is correctly formatted and contains valid data values.

ERROR_INSUFFICIENT_BUFFER

122 (0x7A)

The data area passed to a system call is too small. The actual size of the property list buffer as determined by the Cluster service is larger than the size specified in the cbInBufferSize parameter.

ERROR_INVALID_DATA

13 (0xD)

The data is invalid. The property list is either formatted incorrectly or contains invalid data, such as an out-of-range value.

ERROR_INVALID_PARAMETER

87 (0x57)

The parameter is incorrect. The property list is not formatted correctly.

RPC_X_BAD_STUB_DATA

1783 (0x6F7)

The stub received bad data. The lpInBuffer parameter is NULL.

System error code

If any other value is returned, then the operation failed.

Remarks

By default, failover clusters do not define any private properties for groups. However, you can use the CLUSCTL_GROUP_SET_PRIVATE_PROPERTIES control code to define private properties for a group.

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.
