FSCTL_GET_REPARSE_POINT IOCTL

-description

Retrieves the reparse point data associated with the file or directory identified by the specified handle.

To perform this operation, call the DeviceIoControl function with the following parameters.

BOOL DeviceIoControl(
  (HANDLE) hDevice,             // handle to file or directory
  FSCTL_GET_REPARSE_POINT,      // dwIoControlCode
  NULL,                         // lpInBuffer
  0,                            // nInBufferSize
  (LPVOID) lpOutBuffer,         // output buffer
  (DWORD) nOutBufferSize,       // size of output buffer
  (LPDWORD) lpBytesReturned,    // number of bytes returned
  (LPOVERLAPPED) lpOverlapped   // OVERLAPPED structure
);

-input-buffer

-input-buffer-length

-output-buffer

-output-buffer-length

-in-out-buffer

-status-block

Irp->IoStatus.Status is set to STATUS_SUCCESS if the request is successful.

Otherwise, Status is set to the appropriate error condition as a NTSTATUS code.

For more information, see NTSTATUS Values.

-remarks

For the implications of overlapped I/O on this operation, see the Remarks section of DeviceIoControl.

In Windows 8 and Windows Server 2012, this code is supported by the following technologies.

Technology Supported
Server Message Block (SMB) 3.0 protocol Yes
SMB 3.0 Transparent Failover (TFO) Yes
SMB 3.0 with Scale-out File Shares (SO) Yes
Cluster Shared Volume File System (CsvFS) No
Resilient File System (ReFS) Yes

CsvFs does not support reparse points.
