IOCTL_STORAGE_MEDIA_REMOVAL IOCTL (winioctl.h)

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.

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

Remarks

The IOCTL_STORAGE_MEDIA_REMOVAL control code is valid only for devices that support removable media.
