The basic procedure for protecting against leaks is to acquire each source owned by a useful resource tackle with a suitable destructor. A checker can find “naked news”. Offered an index of C-design allocation capabilities (e.g., fopen()), a checker can also uncover employs that are not managed by a useful resource cope with.
