Access to struct members is provided only via public functions. You can always look at source files - libdm/ioctl/libdm-targets.h - but as mentioned earlier - forget about using a copy of this struct in your tools - there is only public access - as the structure content may freely change between release of libdevmapper - which would have made you binary incompatible.
