use create_eyetracker.c is fail

[杨西]

I use python discover_glasses_on_network.py is

import socket
import struct

MULTICAST_ADDR = ‘ff02::1’ # ipv6: all nodes on the local network segment
PORT = 13007

if __name__ == ‘__main__’:

s6 = socket.socket(socket.AF_INET6, socket.SOCK_DGRAM)
s6.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
s6.bind((‘fe80::fc50:54de:2271:25bd%11’, PORT))
#s6.bind((‘fe80::492:abf:8c99:c340%18’, PORT))

s6.sendto(‘{“type”:”discover”}’, (MULTICAST_ADDR, 13006))

print (“Press Ctrl-C to abort…”)
while True:
data, address = s6.recvfrom(1024)
print (” From: ” + address[0] + ” ” + data)

print data is :
From: fe80::76fe:48ff:fe1c:9646%11 {“type”:”identity”,”class”:”glasses2″,”name”
:”TG02B-080107110661″,”version”:”1.22.0-zucchinipaj”,”id”:”TG02B-080107110661″,”
port”:80,”interface”:”eth0″,”ipv4″:”192.168.1.141″}

but when i use c code, file create_eyetracker.c

#include <stdio.h>
#include “tobii_research.h”
#include “tobii_research_eyetracker.h”
void create_eyetracker_example(char* address) {
// ex address = “tet-tcp://12.13.14.15”
TobiiResearchEyeTracker* eyetracker = NULL;
TobiiResearchStatus status = tobii_research_get_eyetracker(address, &eyetracker);
char* serial_number;
char* device_name;
char* model;
tobii_research_get_serial_number(eyetracker, &serial_number);
tobii_research_get_device_name(eyetracker, &device_name);
tobii_research_get_model(eyetracker, &model);
printf(“Get Eye tracker with status: %i”, status);
printf(“Address: %s\n”, address);
printf(“Model: %s\n”, model);
printf(“Name (It’s OK if this is empty): %s\n”, device_name);
printf(“Serial number: %s\n”, serial_number);
tobii_research_free_string(serial_number);
tobii_research_free_string(device_name);
tobii_research_free_string(model);
}

int main()
{
create_eyetracker_example(“tet-tcp://192.168.1.141”);
return 0;
}

eyetracker value is NULL.
