CLUSCTL_RESOURCE_TYPE_GET_RO_PRIVATE_PROPERTIES control code

Artikel

Retrieves the read-only private properties for a resource type. Applications use this control code as a parameter to the ClusterResourceTypeControl function, and resource DLLs receive the control code as a parameter to the ResourceTypeControl callback function.

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

Parameters

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

lpOutBuffer: On a successful return, points to a property list containing the resource type's read-only private properties.

Return value

ClusterResourceTypeControl returns one of the following values.

ERROR_SUCCESS

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

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

ClusAPI.h defines the 32 bits of CLUSCTL_RESOURCE_TYPE_GET_RO_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_GET_RO_PRIVATE_PROPERTIES (0x7d)
Access code	0 1	CLUS_ACCESS_READ (0x1)

Resource DLL Support

Conditional. If your resource type has read-only private properties, support the CLUSCTL_RESOURCE_TYPE_GET_RO_PRIVATE_PROPERTIES control code in your implementation of ResourceTypeControl. Return a property list that includes all of the read-only properties specific to your resource type. Remember to terminate the list with CLUSPROP_SYNTAX_ENDMARK, an enumerator from the CLUSTER_PROPERTY_SYNTAX enumeration. For more information on working with property lists, see Creating Property Lists.

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.
