KsSetInformationFile function (ks.h)
The KsSetInformationFile function performs an information set against the specified file object. The function attempts to use FastIoDispatch if possible, or it generates an information set against the device object.
Syntax
KSDDKAPI NTSTATUS KsSetInformationFile(
[in] PFILE_OBJECT FileObject,
[in] PVOID FileInformation,
[in] ULONG Length,
[in] FILE_INFORMATION_CLASS FileInformationClass
);
Parameters
[in] FileObject
Specifies the file object to set the standard information on.
[in] FileInformation
Indicates the place in which to put the file information. The file information is assumed to be a valid or probed address.
[in] Length
Specifies the correct length of the FileInformation buffer.
[in] FileInformationClass
Specifies the class of information being set.
Return value
The KsSetInformationFile function returns STATUS_SUCCESS if successful, or if unsuccessful it returns a set error.
Remarks
The KsSetInformationFile function should be used only when the set would result in an actual request to the underlying driver, not including complex operations that require additional parameters to be sent to the driver such as rename, deletion, and completion. For example, FilePositionInformation would not generate such a request and should not be used. It assumes the caller is serializing access to the file for operations against a FO_SYNCHRONOUS_IO file object.
