Suggest you follow this example from current libiptc:

/* Flushes the entries in the given chain (ie. empties chain). */
int
TC_FLUSH_ENTRIES(const IPT_CHAINLABEL chain, TC_HANDLE_T *handle)
{       
        unsigned int startindex, endindex;
        STRUCT_ENTRY *startentry, *endentry;
        struct chain_cache *c;
        int ret;

        iptc_fn = TC_FLUSH_ENTRIES;
        if (!(c = find_label(chain, *handle))) {
                errno = ENOENT;
                return 0;
        }               
        startindex = offset2index(*handle, c->start_off);
        endindex = offset2index(*handle, c->end_off);
        startentry = offset2entry(*handle, c->start_off);
        endentry = offset2entry(*handle, c->end_off);
                
        ret = delete_rules(endindex - startindex,
                           (char *)endentry - (char *)startentry,
                           c->start_off, startindex,
                           handle);
        return ret;
}
