好的，这里是根据你提供的结构体修改后的函数：

int vrrp_route_del_cmd(vrrp_route_t *route_info) {
    if (route_info == NULL) {
        return -1;
    }

    for (int i = 0; i < route_number; i++) {
        vrrp_route_t *p_del = route_ptr_s - i;

        if (route_info->version != p_del->version) { // 版本不同直接跳过
            continue;
        }

        if (route_info->version == 1 && strcmp(route_info->ipv4_info.destination, p_del->ipv4_info.destination) == 0 
                && strcmp(route_info->ipv4_info.genmask, p_del->ipv4_info.genmask) == 0 
                && route_info->ipv4_info.table_id == p_del->ipv4_info.table_id) { // IPv4 路由表项匹配
            if (i == 0) {
                memset(p_del, 0, sizeof(vrrp_route_t));
            } else {
                memcpy(p_del, p_del + 1, i * sizeof(vrrp_route_t));
                memset(route_ptr_s - i + route_number - 1, 0, sizeof(vrrp_route_t));
            }
            route_number--;

            if (route_number == 0) { // 如果路由表为空，则释放内存并重置相关变量
                V2V_SYSLOG_INFO("Route table is empty\n");
                free(route_ptr);
                route_ptr = NULL;
                route_ptr_s = NULL;
                route_apply_amount = 0;
            } else {
                route_ptr_s--;
            }

            return 0;
        } else if (route_info->version == 2 && memcmp(&route_info->ipv6_info.destination, &p_del->ipv6_info.destination, sizeof(struct in6_addr)) == 0 
                && route_info->ipv6_info.prefixlen == p_del->ipv6_info.prefixlen 
                && route_info->ipv6_info.table_id == p_del->ipv6_info.table_id) { // IPv6 路由表项匹配
            if (i == 0) {
                memset(p_del, 0, sizeof(vrrp_route_t));
            } else {
                memcpy(p_del, p_del + 1, i * sizeof(vrrp_route_t));
                memset(route_ptr_s - i + route_number - 1, 0, sizeof(vrrp_route_t));
            }
            route_number--;

            if (route_number == 0) { // 如果路由表为空，则释放内存并重置相关变量
                V2V_SYSLOG_INFO("Route table is empty\n");
                free(route_ptr);
                route_ptr = NULL;
                route_ptr_s = NULL;
                route_apply_amount = 0;
            } else {
                route_ptr_s--;
            }

            return 0;
        }
    }

    V2V_SYSLOG_INFO("Failed to find the specified route\n");
    return -1;
}
