I agree that's less than ideal,
but I still don't see a way around contiguous char * strings,
because that's what most 'legacy' libraries want.

You can add that as a layer around the next EPICS String class
and copy char by char from the non-contig. String into a char *,
but std::string and MFC::CString instead bite the bullet
and provide a c_str() type of method.
