Verifies that a property list contains valid resource type property names and values and that the list is properly formatted. Applications use this control code as a ClusterResourceTypeControl parameter, and resource DLLs receive the control code as a ResourceTypeControl parameter.

ClusterResourceTypeControl( hCluster,                                          // cluster handle
                            lpszResTypeName,                                   // resource type name
                            hHostNode,                                         // optional host node
                            CLUSCTL_RESOURCE_TYPE_VALIDATE_PRIVATE_PROPERTIES, // this control code
                            lpInBuffer,                                        // input buffer: property list
                            cbInBufferSize,                                    // allocated buffer size (bytes)
                            NULL,                                              // output buffer: (not used)
                            0,                                                 // output buffer size (not used)
                            NULL );                                            // actual size of resulting data (not used)

Parameters

The following control code function and DLL support parameters are specific to this control code. For complete parameter descriptions, see ClusterResourceTypeControl or ResourceTypeControl.

lpInBuffer: Points to a property list containing one or more read/write private resource type properties.

Return value

ClusterResourceTypeControl returns one of the following values.

ERROR_SUCCESS

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.

RPC_X_BAD_STUB_DATA

1783 (0x6F7)

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

System error code

If any value is returned, then the operation failed.

Remarks

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

ClusAPI.h defines the 32 bits of CLUSCTL_RESOURCE_TYPE_VALIDATE_PRIVATE_PROPERTIES as follows (for more information, see Control Code Architecture).

Component	Bit location	Value
Object code	24 31	CLUS_OBJECT_RESOURCE_TYPE (0x2)
Global bit	23	CLUS_NOT_GLOBAL (0x0)
Modify bit	22	CLUS_NO_MODIFY (0x0)
User bit	21	CLCTL_CLUSTER_BASE (0x0)
Type bit	20	External (0x0)
Operation code	0 23	CLCTL_VALIDATE_PRIVATE_PROPERTIES (0x89)
Access code	0 1	CLUS_ACCESS_READ (0x1)

Resource DLL Support

Required. Always support the CLUSCTL_RESOURCE_TYPE_VALIDATE_PRIVATE_PROPERTIES control code. Your implementation should parse the property list passed in the InBuffer parameter, verifying that each property value is valid for the resource type.

If you do not support this control code, the Resource Monitor verifies that the property list is formatted correctly but does not actually validate the data. This can result in the assignment of invalid property values.

As a general guideline, the Resource Monitor should handle all of the control codes for common properties, while your DLL should handle all control codes for private properties.

For more information on the ResourceTypeControl entry point, see Implementing ResourceTypeControl.

Requirements


Minimum supported client	None supported
Minimum supported server	Windows Server 2008 Enterprise, Windows Server 2008 Datacenter
Header	ClusAPI.h
