Properties

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.
