FSCTL_DELETE_REPARSE_POINT IOCTL

Description

Deletes a reparse point from the specified file or directory. Using FSCTL_DELETE_REPARSE_POINT does not delete the file or directory.

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

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

Parameters

Input buffer

Input buffer length

Output buffer

Output buffer length

Input/output buffer

Input/output buffer length

Status block

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

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

For more information, see NTSTATUS Values.

Remarks

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.

FSCTL_DELETE_REPARSE_POINT control code

The FSCTL_DELETE_REPARSE_POINT control code deletes a reparse point from the specified file or directory. Using FSCTL_DELETE_REPARSE_POINT does not delete the file or directory.

To perform this operation, call ZwFsControlFile with the following parameters.

Minifilters should use FltUntagFile instead of FSCTL_DELETE_REPARSE_POINT to delete a reparse point.

For more information about reparse points and the FSCTL_DELETE_REPARSE_POINT control code, see the Microsoft Windows SDK documentation.

Parameters

Status block

ZwFsControlFile returns STATUS_SUCCESS or an appropriate NTSTATUS value such as one of the following:

Code Meaning
STATUS_IO_REPARSE_DATA_INVALID One of the specified parameter values was invalid. This is an error code.
STATUS_IO_REPARSE_TAG_INVALID The reparse tag specified by the caller was invalid. This is an error code.
STATUS_IO_REPARSE_TAG_MISMATCH The reparse tag specified by the caller did not match the tag of the reparse point to be deleted. This is an error code.
STATUS_REPARSE_ATTRIBUTE_CONFLICT The reparse point is a third-party reparse point, and the reparse GUID specified by the caller did not match the GUID of the reparse point to be deleted. This is an error code.
