gsoap and resource management

Question

I use gsoap to implement some Web-service in my C program.

I use gsoap like this:

int motion_detector_check_status(const char *endpoint, 
        const motion_detector_subscription_result_t *sr, int *status) {
    int rc = EXIT_SUCCESS;
    double _timeout = difftime(sr->termination_time, sr->current_time);
    char timeout[TIMEOUT_MAX_LEN];
    struct soap *soap = soap_new();
    struct _tev__PullMessages request;
    struct _tev__PullMessagesResponse response;
    char *motion_state;

    if (!soap) return EXIT_FAILURE;

    snprintf(timeout, TIMEOUT_MAX_LEN, "PT%.0fS", _timeout < 5.0 ? _timeout : 5.0);

    request.MessageLimit = 1;
    request.Timeout = _timeout < 5.0 ? (int64_t)_timeout : 5.0;
    request.__any = timeout;
    request.__size = sizeof(timeout) + 1;

    rc = soap_call___tev__PullMessages(soap, endpoint, SOAP_ACTION_PULL_MESSAGE,
            &request, &response);

    if (rc != SOAP_OK) {
        soap_print_fault(soap, stderr);
        goto end;
    }

    if (response.wsnt__NotificationMessage && 
            response.wsnt__NotificationMessage->Topic &&
            response.wsnt__NotificationMessage->Topic->__any) {
        if (strstr(response.wsnt__NotificationMessage->Topic->__any, MOTION_ALARM_SRC)) {
            motion_state = strstr(response.wsnt__NotificationMessage->Message.__any,
                    "<tt:SimpleItem Name=\"State\" Value=");

            if (strcasestr(motion_state, "true"))
                *status = 1;
            else
                *status = 0;
        }
    }

    motion_detector_check_status_free_response(&response);
end:
    soap_end(soap);
    soap_destroy(soap);
    soap_free(soap);
    return rc;
}

Everything works well, but struct _tev__PullMessagesResponse has some pointers to char and other structures.

When I run my program in valgring it told me that I have memory leaks and resources referenced through pointers inside response aren't free after end of motion_detector_check_status. Of course I could write this functions by myself, but I'm wonder does gsoap provides functions to free this resources?

Thanks in advance, and sorry for my English.

Well, walking deeper throught docomentation to soapcpp2 I found option -Ed witch generates soap_del_T macros for each type used by gsoap.
