/*
 * The create/open option flags: used in NtCreateAndx and NtTransactCreate
 * SMB requests.
 *
 * The CreateOptions specify the options to be applied when creating or
 * opening the file, as a compatible combination of the following flags:
 *
 * FILE_DIRECTORY_FILE
 *	The file being created or opened is a directory file. With this
 *	flag, the Disposition parameter must be set to one of FILE_CREATE,
 *	FILE_OPEN, or FILE_OPEN_IF. With this flag, other compatible
 *	CreateOptions flags include only the following:
 *			FILE_SYNCHRONOUS_IO_ALERT
 *			FILE_SYNCHRONOUS_IO_NONALERT
 *			FILE_WRITE_THROUGH
 *			FILE_OPEN_FOR_BACKUP_INTENT
 *			FILE_OPEN_BY_FILE_ID
 *
 * FILE_NON_DIRECTORY_FILE
 *	The file being opened must not be a directory file or this call
 *	will fail. The file object being opened can represent a data file,
 *	a logical, virtual, or physical device, or a volume.
 *
 * FILE_WRITE_THROUGH
 *	System services, FSDs, and drivers that write data to the file must
 *	actually transfer the data into the file before any requested write
 *	operation is considered complete. This flag is automatically set if
 *	the CreateOptions flag FILE_NO_INTERMEDIATE _BUFFERING is set.
 *
 * FILE_SEQUENTIAL_ONLY
 *	All accesses to the file will be sequential.
 *
 * FILE_RANDOM_ACCESS
 *	Accesses to the file can be random, so no sequential read-ahead
 *	operations should be performed on the file by FSDs or the system.
 *	FILE_NO_INTERMEDIATE _BUFFERING	The file cannot be cached or
 *	buffered in a driver's internal buffers. This flag is incompatible
 *	with the DesiredAccess FILE_APPEND_DATA flag.
 *
 * FILE_SYNCHRONOUS_IO_ALERT
 *	All operations on the file are performed synchronously. Any wait
 *	on behalf of the caller is subject to premature termination from
 *	alerts. This flag also causes the I/O system to maintain the file
 *	position context. If this flag is set, the DesiredAccess
 *	SYNCHRONIZE flag also must be set.
 *
 * FILE_SYNCHRONOUS_IO _NONALERT
 *	All operations on the file are performed synchronously. Waits in
 *	the system to synchronize I/O queuing and completion are not subject
 *	to alerts. This flag also causes the I/O system to maintain the file
 *	position context. If this flag is set, the DesiredAccess SYNCHRONIZE
 *	flag also must be set.
 *
 * FILE_CREATE_TREE _CONNECTION
 *	Create a tree connection for this file in order to open it over the
 *	network. This flag is irrelevant to device and intermediate drivers.
 *
 * FILE_COMPLETE_IF_OPLOCKED
 *	Complete this operation immediately with an alternate success code
 *	if the target file is oplocked, rather than blocking the caller's
 *	thread. If the file is oplocked, another caller already has access
 *	to the file over the network. This flag is irrelevant to device and
 *	intermediate drivers.
 *
 * FILE_NO_EA_KNOWLEDGE
 *	If the extended attributes on an existing file being opened indicate
 *	that the caller must understand EAs to properly interpret the file,
 *	fail this request because the caller does not understand how to deal
 *	with EAs. Device and intermediate drivers can ignore this flag.
 *
 * FILE_DELETE_ON_CLOSE
 *	Delete the file when the last reference to it is passed to close.
 *
 * FILE_OPEN_BY_FILE_ID
 *	The file name contains the name of a device and a 64-bit ID to
 *	be used to open the file. This flag is irrelevant to device and
 *	intermediate drivers.
 *
 * FILE_OPEN_FOR_BACKUP _INTENT
 *	The file is being opened for backup intent, hence, the system should
 *	check for certain access rights and grant the caller the appropriate
 *	accesses to the file before checking the input DesiredAccess against
 *	the file's security descriptor. This flag is irrelevant to device
 *	and intermediate drivers.
