back at the naming bikeshed

so I found myself writing this macro, and using it 4 times. +#define for_each_boxed_veclen(_box, _vec, _len, _ct, _curs) \ + for (_ct = 0, _curs = _box->_vec; _ct < _box->_len; _ct++, _curs++) - for (i = 0, cm = di->classes; i < di->num_classes; i++, cm++) { + for_each_boxed_veclen(di, classes, num_classes, i, cm) { Qs: does it exist by another name already ? is it worth having generally ? are there better ways to do it ? fwiw, it does sound semantically connected to __counted_by() attribute struct Ntuple { int len; struct tuple **vector __counted_by(len); }
