CLUSCTL_RESOURCE_TYPE_ENUM_PRIVATE_PROPERTIES control code
Retrieves a list of the read/write and read-only resource type private properties. 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_ENUM_PRIVATE_PROPERTIES, // this control code
NULL, // input buffer (not used)
0, // input buffer size (not used)
lpOutBuffer, // output buffer: array of strings
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, contains an array of null-terminated Unicode strings with an additional NULL terminator appended to the last string. Each string in the array contains the name of a read/write private resource type property.
Return value
ClusterResourceTypeControl returns one of the following values.
-
ERROR_SUCCESS
-
0
The operation completed successfully.
-
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.
-
If any other value is returned, then the operation failed. The value of lpcbBytesReturned is unreliable.
Remarks
The CLUSCTL_RESOURCE_TYPE_ENUM_PRIVATE_PROPERTIES control code returns only property names, not property values. To retrieve values for common resource type properties, use CLUSCTL_RESOURCE_TYPE_GET_PRIVATE_PROPERTIES and CLUSCTL_RESOURCE_TYPE_GET_RO_PRIVATE_PROPERTIES.

ClusAPI.h defines the 32 bits of CLUSCTL_RESOURCE_TYPE_ENUM_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_ENUM_PRIVATE_PROPERTIES (0x79) |
| Access code | 0 1 | CLUS_ACCESS_READ (0x1) |
Resource DLL Support
Required. Always support the CLUSCTL_RESOURCE_TYPE_ENUM_PRIVATE_PROPERTIES control code by returning the names of the resource type's private properties in the OutBuffer parameter.
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.
