KsDispatchFastReadFailure function

Description

The KsDispatchFastReadFailure function is used in a KSDISPATCH_TABLE.FastRead entry when fast I/O read is not handled. The function should always return FALSE.

Parameters

FileObject [in]

Not used.

FileOffset [in]

Not used.

Length [in]

Not used.

Wait [in]

Not used.

LockKey [in]

Not used.

Buffer [out]

Not used.

IoStatus [out]

Not used.

DeviceObject [in]

Not used.

Return value

The KsDispatchFastReadFailure function returns FALSE.

Remarks

The KsDispatchFastReadFailure 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 KsDispatchFastReadFailure function, that calls a dispatch table entry.
