Um, maybe not? Since my code would go
pVecServices->create_vet(....,pszNewVecHanBuff);
//got new vec now
//later; put a com handle in iNdx'th eelement of vector
pVecServices->set_vec(pszNewVecHanBuff, iNdx,
pszNewCommHanBuff);
In this case I can absolutely guarantee that vector element iNdx had nothing in
it before I called pVecServices->set_vec, since vec is clean shiny new. If I
understand ppsv->changerefhandle, now no chance I'm overwritting something that
needed ref counting.
