PERF_INSTANCE_DEFINITION (Windows Embedded CE 6.0)
1/5/2010
This structure contains the instance-specific information for a block of performance data.
There is one PERF_INSTANCE_DEFINITION structure for each instance specified in the PERF_OBJECT_TYPE structure.
typedef struct _PERF_INSTANCE_DEFINITION {
DWORD ByteLength;
DWORD ParentObjectTitleIndex;
DWORD ParentObjectInstance;
DWORD UniqueID;
DWORD NameOffset;
DWORD NameLength;
} PERF_INSTANCE_DEFINITION;
Members
- ByteLength
Specifies the length, in bytes, of this structure, including the subsequent name.
ParentObjectTitleIndex
Specifies the index of the name of the parent object in the title database.For example, if the object is a thread, the parent object type is a process, or if the object is a logical drive, the parent is a physical drive.
ParentObjectInstance
Specifies the index to an instance of the parent object type that is the parent of this instance.This member might be 0 (zero) or greater.
UniqueID
Specifies the unique identifier used instead of the instance name.This value of this member is PERF_NO_UNIQUE_ID if there is no such identifier.
- NameOffset
Specifies the offset from the beginning of this structure to the Unicode name of this instance.
NameLength
Specifies the length, in bytes, of the instance name.This member is 0 (zero) if the instance does not have a name.
