Calling Expect Script from C++

[daljman]

I have written an Expect Script that I need to call from a testcase written in C++. I need the Expect script to be called prior to and after the testcase has done its magic.

Question: How do you call an Expect Script from C++.

Here's my C++ testcase:

====================================================
@TCID: ip99_expect
@GAP_PACKAGE:
set_reserve_timeout(60);
set_trace("LOGGING","ON"
GTP_TRACE="ON";

ip99_expect(resource_name1="gtp:sgsn_shasta_52",
resource_name3="msca:imsi_multi"

@GAP_TC:
#include <tc/TTF.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <gtp_codec/GTP_prot.h>
#include <gtp_ts/GTPTunnel.h>
#include <bss_ts/Mobile.h>

GTPTunnel sgsn(&quot;resource_name1&quot;, &quot;no_default&quot;
Mobile ms(&quot;resource_name3&quot;, &quot;no_default&quot;

//----------------------
// user_main
//----------------------
void ohm_main(void)
{
TTF_Result result;
SS7_Msg msg;
TTF_String imsi = &quot;5050241012160001&quot;;
TTF_String euAddress;
TTF_String steid;
TTF_String pdpAddress;
uint8 pdpType = 0;
uint8 nsapi = 4;


// Set up routing
sgsn.setPrimaryRouting(imsi, nsapi);

///////I want to call my script here
