Retrieves a list of the read/write resource common property names. Applications use this control code as a ClusterResourceControl parameter, and resource DLLs receive the control code as a ResourceControl parameter.

  hResource,                                         // resource handle
  hHostNode,                                         // optional host node
  CLUSCTL_RESOURCE_ENUM_COMMON_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)


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


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 common resource property.

Return value

ClusterResourceControl returns one of the following values.



The operation completed successfully.

System error code

If any other value is returned then the operation failed. The value of lpcbBytesReturned is unreliable.

Implementations of ResourceControl can return the above values or the following value.



Incorrect function. Requests that the Resource Monitor perform default processing (if any) for the control code addition to processing supplied by the DLL (if any).


The CLUSCTL_RESOURCE_ENUM_COMMON_PROPERTIES control code returns only property names, not property values. To retrieve values for common resource properties, use CLUSCTL_RESOURCE_GET_COMMON_PROPERTIES and CLUSCTL_RESOURCE_GET_RO_COMMON_PROPERTIES. For more information, see Getting Information with Control Codes.

Do not use the CLUSCTL_RESOURCE_ENUM_COMMON_PROPERTIES control code in any resource DLL entry point function. This control code can safely be called from a worker thread. For more information, see Function Calls to Avoid in Resource DLLs.

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

Component Bit location Value
Object code 24 31 CLUS_OBJECT_RESOURCE (0x1)
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_COMMON_PROPERTIES (0x51)
Access code 0 1 CLUS_ACCESS_READ (0x1)

Resource DLL Support

Use default. Return ERROR_INVALID_FUNCTION to let the Resource Monitor build the list of property names.

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 ResourceControl entry point function, see Implementing ResourceControl.
