FileIo_OpEnd class
This class is the event type class for file operation end events.
The following syntax is simplified from MOF code.
[EventType{76}, EventTypeName{"OperationEnd"}]
class FileIo_OpEnd : FileIo
{
uint32 IrpPtr;
uint32 ExtraInfo;
uint32 NtStatus;
};
The FileIo_OpEnd class has these types of members:
The FileIo_OpEnd class has these properties.
-
ExtraInfo
-
-
Data type: uint32
-
Access type: Read-only
-
Qualifiers: WmiDataId(2), Pointer
Extra information returned by the file system for the operation. For example for a read request, the actual number of bytes that were read.
-
-
IrpPtr
-
-
Data type: uint32
-
Access type: Read-only
-
Qualifiers: WmiDataId(1), Pointer
IO request packet. This property identifies the IO activity that is ending.
-
-
NtStatus
-
-
Data type: uint32
-
Access type: Read-only
-
Qualifiers: WmiDataId(3)
Return value from the operation.
-
FileIo events are logged at the beginning of the operation. OpEnd events can be enabled separately to indicate the end of those operations. Irp can be used to correlate the begin and end events.
