FILE_REPARSE_POINT_INFORMATION structure (ntifs.h)
The FILE_REPARSE_POINT_INFORMATION structure is used to query for information about a reparse point.
Syntax
typedef struct _FILE_REPARSE_POINT_INFORMATION {
LONGLONG FileReference;
ULONG Tag;
} FILE_REPARSE_POINT_INFORMATION, *PFILE_REPARSE_POINT_INFORMATION;
Members
FileReference
The 8-byte file reference number for the file. NTFS generates this number and assigns it to the file automatically when the file is created.
Tag
The reparse point tag that indicates the structure of the reparse data. See About reparse points for more information about reparse point tags.
Remarks
This information can be queried in either of the following ways:
Call ZwQueryDirectoryFileEx, passing FileReparsePointInformation as the value of FileInformationClass and passing a caller-allocated, FILE_REPARSE_POINT_INFORMATION-structured buffer as the value of FileInformation.
Create an IRP with major function code IRP_MJ_DIRECTORY_CONTROL and minor function code IRP_MN_QUERY_DIRECTORY.
No specific access rights are required to query this information.
This structure must be LONG-aligned.
See About reparse points for more information about reparse points.
