Contains resource class data. It is used as the data member of a CLUSPROP_RESOURCE_CLASS_INFO structure and as the return value of some control code operations.
Syntax

union {
struct {
union {
DWORD dw;
CLUSTER_RESOURCE_CLASS rc;

Members
DUMMYUNIONNAME
DUMMYUNIONNAME.DUMMYSTRUCTNAME
DUMMYUNIONNAME.DUMMYSTRUCTNAME.DUMMYUNIONNAME
DUMMYUNIONNAME.DUMMYSTRUCTNAME.DUMMYUNIONNAME.dw
Provides another way to access the resource class data.
DUMMYUNIONNAME.DUMMYSTRUCTNAME.DUMMYUNIONNAME.rc
Resource class described with one of the following values enumerated from the CLUSTER_RESOURCE_CLASS enumeration.
####### DUMMYSTRUCTNAME.DUMMYUNIONNAME.rc.CLUS_RESCLASS_UNKNOWN (0)
Resource class is unknown.
####### DUMMYSTRUCTNAME.DUMMYUNIONNAME.rc.CLUS_RESCLASS_STORAGE (1)
Resource is a storage device, such as a Physical Disk resource.
####### DUMMYSTRUCTNAME.DUMMYUNIONNAME.rc.CLUS_RESCLASS_NETWORK (2)
Resource is a network device.
####### DUMMYSTRUCTNAME.DUMMYUNIONNAME.rc.CLUS_RESCLASS_USER (32768 (0x8000))
Resource classes beginning at this value are user-defined.
DUMMYUNIONNAME.DUMMYSTRUCTNAME.SubClass
A mask value that further describes the resource class. The following value is valid for storage class resources such as Physical Disk resources.
DUMMYSTRUCTNAME.SubClass.CLUS_RESSUBCLASS_SHARED (0x80000000)
Indicates that the resource manages a shared resource such as a disk on a shared SCSI bus.
DUMMYUNIONNAME.li
Resource class and subclass described as a ULARGE_INTEGER value with a low DWORD and a high DWORD.
Remarks
A resource class identifies resources of similar capability. A resource DLL that defines its own resource class should provide a unique identifier for the class that is set to a value greater than CLUS_RESCLASS_USER. CLUS_RESCLASS_USER specifies the beginning for user-defined resource class identifiers.
A CLUS_RESOURCE_CLASS_INFO structure is returned by ClusterResourceControl when the dwControlCode parameter is set to CLUSCTL_RESOURCE_GET_CLASS_INFO and is returned by ClusterResourceTypeControl when dwControlCode is set to CLUSCTL_RESOURCE_TYPE_GET_CLASS_INFO.
