QUERY_ON_CREATE_USN_INFORMATION structure (ntifs.h)
The QUERY_ON_CREATE_USN_INFORMATION structure is used to write file information when FltRequestFileInfoOnCreateCompletion is called with the QoCFileUsnInformation flag set in the InfoClassFlags parameter.
Syntax
typedef struct _QUERY_ON_CREATE_USN_INFORMATION {
USN Usn;
FILE_ID_128 FileReferenceNumber;
} QUERY_ON_CREATE_USN_INFORMATION, *PQUERY_ON_CREATE_USN_INFORMATION;
Members
Usn
The USN (Update Sequence Number) for this file or directory.
FileReferenceNumber
The 128-bit file ID (aka ordinal number) of the file or directory.
Remarks
The system allocates this structure and the file system fills in the requested information, if supported, while it processes a file create. Filter Manager will eventually free the allocated structure.
