FSCTL_TXFS_SAVEPOINT_INFORMATION IOCTL (winioctl.h)

  • Article

Note

Microsoft strongly recommends developers utilize alternative means to achieve your application’s needs. Many scenarios that TxF was developed for can be achieved through simpler and more readily available techniques. Furthermore, TxF may not be available in future versions of Microsoft Windows. For more information, and alternatives to TxF, please see Alternatives to using Transactional NTFS.

The FSCTL_TXFS_SAVEPOINT_INFORMATION control code controls setting, clearing, and rolling back to the specified savepoint.

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

BOOL DeviceIoControl(
  (HANDLE) hDevice,                 // handle to resource manager
  FSCTL_TXFS_SAVEPOINT_INFORMATION, // dwIoControlCode
  (LPVOID)lpInBuffer ,              // input buffer
  (DWORD) nInBufferSize,            // size of input buffer
  (LPVOID) lpOutBuffer,             // output buffer
  (DWORD) nOutBufferSize,           // size of output buffer
  (LPDWORD) lpBytesReturned,        // number of bytes returned
  (LPOVERLAPPED) lpOverlapped       // OVERLAPPED structure
);
