[EventType{69, 70, 71, 74, 75}, EventTypeName{"SetInfo", "Delete", "Rename", "QueryInfo", "FSControl"}]
class FileIo_Info : FileIo
{

  uint32 ExtraInfo;
  uint32 InfoClass;
};

Members

The FileIo_Info class has these types of members:

Properties

The FileIo_Info class has these properties.

ExtraInfo

Data type: uint32

Access type: Read-only

Qualifiers: WmiDataId(5), Pointer

For FileDispositionInformation requests, this field contains the requested disposition. For FileEndOfFileInformation and FileAllocationInformation requests, this field contains the specified file size.

FileKey

Data type: uint32

Access type: Read-only

Qualifiers: WmiDataId(4), Pointer

To determine the file name, match the value of this property to the FileObject property of a FileIo_Name event.

FileObject

Data type: uint32

Access type: Read-only

Qualifiers: WmiDataId(3), Pointer

Identifier that can be used for correlating operations to the same opened file object instance between file create and close events.

InfoClass

Data type: uint32

Access type: Read-only

Qualifiers: WmiDataId(6)

Requested file information class.

IrpPtr

Data type: uint32

Access type: Read-only

Qualifiers: WmiDataId(1), Pointer

IO request packet. This property identifies the IO activity.

TTID

Data type: uint32

Access type: Read-only

Qualifiers: WmiDataId(2), Pointer

Thread identifier of the thread that is performing the operation.

Remarks

Set information and query information events indicate that the file attributes were set or queried. A file system control (FSControl) event is recorded when a FSCTL command is issued.
