FSCTL_DELETE_REPARSE_POINT IOCTL (winioctl.h)

  • Article

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
);
