CLUSCTL_RESOURCE_TYPE_UNKNOWN control code
This control code verifies that control codes are being processed on the node where execution of the control is directed. 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_UNKNOWN, // this control code
NULL, // input buffer: (not used)
0, // input buffer size (not used)
NULL, // output buffer: (not used)
0, // output buffer size (not used)
NULL ); // actual size of resulting data (not used)
Parameters
For complete parameter descriptions, see ClusterResourceTypeControl or ResourceTypeControl. This control code has no parameters associated with it.
Return value
When an application uses CLUSCTL_RESOURCE_TYPE_UNKNOWN as a parameter for ClusterResourceTypeControl, ClusterResourceTypeControl always returns ERROR_SUCCESS.
Remarks
ClusAPI.h defines the 32 bits of CLUSCTL_RESOURCE_TYPE_UNKNOWN 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_UNKNOWN (0x0) |
| Access code | 0 1 | CLUS_ACCESS_READ (0x1) |
Resource DLL Support
Conditional. If your DLL supports any other resource type control codes for the indicated resource type, return ERROR_SUCCESS. Otherwise, return ERROR_INVALID_FUNCTION.
