KsDispatchFastWriteFailure function

The KsDispatchFastWriteFailure function is used in a KSDISPATCH_TABLE.FastWrite entry when fast I/O is not handled for a write operation. The function should always return FALSE.

Syntax


KSDDKAPI BOOLEAN NTAPI KsDispatchFastWriteFailure(
  _In_   PFILE_OBJECT FileObject,
  _In_   PLARGE_INTEGER FileOffset,
  _In_   ULONG Length,
  _In_   BOOLEAN Wait,
  _In_   ULONG LockKey,
  _In_   PVOID Buffer,
  _Out_  PIO_STATUS_BLOCK IoStatus,
  _In_   PDEVICE_OBJECT DeviceObject
);

Parameters

FileObject [in]

Not used.

FileOffset [in]

Not used.

Length [in]

Not used.

Wait [in]

Not used.

LockKey [in]

Not used.

Buffer [in]

Not used.

IoStatus [out]

Not used.

DeviceObject [in]

Not used.

Return value

The KsDispatchFastWriteFailure function returns FALSE.

Remarks

The KsDispatchFastWriteFailure function is needed since the dispatch table for a particular opened instance of a device may not handle a specific major function that another opened instance needs to handle. Therefore, the function pointer in the driver object must always point to a function, such as the KsDispatchFastWriteFailure function, that calls a dispatch table entry.

Requirements

Header

Ks.h (include Ks.h)
