Here is some code that uses this function -- abt1 is a std::set. {{{ set::iterator endIt1 = abt1.end(); for (unsigned int j0 = 1; j0 <= headCount[0]; ++j0) { // load data into an int named rep. abt1.insert(endIt1, rep); } }}} It is possible someone may want to serialize a non-sorted list to a set. In this case using the hinted insert will be slightly slower than the non-hinted version. This case is somewhat rare though in my opinion.
