IOCTL_CHANGER_EXCHANGE_MEDIUM IOCTL

Moves a piece of media from a source element to one destination, and the piece of media originally in the first destination to a second destination.

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

C++
BOOL DeviceIoControl(
  (HANDLE) hDevice,              // handle to device
  IOCTL_CHANGER_EXCHANGE_MEDIUM, // dwIoControlCode(LPVOID) lpInBuffer,           // input buffer
  (DWORD) nInBufferSize,         // size of input buffer
  NULL,                          // lpOutBuffer0,                             // nOutBufferSize(LPDWORD) lpBytesReturned,     // number of bytes returned
  (LPOVERLAPPED) lpOverlapped    // OVERLAPPED structure
);
