FSCTL_TXFS_CREATE_MINIVERSION IOCTL

Description

[!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.

Creates a new miniversion for the specified file. Miniversions allow you to refer to a snapshot of the file during a transaction. Miniversions are discarded when a transaction is committed or rolled back.

BOOL DeviceIoControl(
  (HANDLE) hDevice,                 // handle to device
  FSCTL_TXFS_CREATE_MINIVERSION,    // 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
);
