IOCTL_STORAGE_MEDIA_REMOVAL IOCTL

Enables or disables the mechanism that ejects media, for those devices possessing that locking capability.

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

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