#ifndef _NTIOAPI_H

//  Flag definitions for NtFlushBuffersFileEx
//
//  If none of the below flags are specified the following will occur for a
//  given file handle:
//      - Write any modified data for the given file from the Windows in-memory
//        cache.
//      - Commit all pending metadata changes for the given file from the
//        Windows in-memory cache.
//      - Send a SYNC command to the underlying storage device to commit all
//        written data in the devices cache to persistent storage.
//
//  If a volume handle is specified:
//      - Write all modified data for all files on the volume from the Windows
//        in-memory cache.
//      - Commit all pending metadata changes for all files on the volume from
//        the Windows in-memory cache.
//      - Send a SYNC command to the underlying storage device to commit all
//        written data in the devices cache to persistent storage.
//
//  This is equivalent to how NtFlushBuffersFile has always worked.
//

//  If set, this operation will write the data for the given file from the
//  Windows in-memory cache.  This will NOT commit any associated metadata
//  changes.  This will NOT send a SYNC to the storage device to flush its
//  cache.  Not supported on volume handles.
