FsRtlValidateReparsePointBuffer function (ntifs.h)

The FsRtlValidateReparsePointBuffer routine verifies that the specified reparse point buffer is valid.

Syntax

NTSTATUS FsRtlValidateReparsePointBuffer(
  [in] ULONG                BufferLength,
  [in] PREPARSE_DATA_BUFFER ReparseBuffer
);

[in] BufferLength

The length of the reparse point buffer.

[in] ReparseBuffer

The FsRtlValidateReparsePointBuffer returns one of the following NTSTATUS values:

Return code	Description
STATUS_SUCCESS	The buffer is valid.
STATUS_IO_REPARSE_DATA_INVALID	The buffer is not valid, such as if the buffer is too long or the length of the buffer and the data length in its header are not consistent.
STATUS_IO_REPARSE_TAG_INVALID	The buffer has an invalid reparse tag.
