Using Stream Engine for DirectX c++ app

[Jamie Steele]

Hey guys, I created the console app starter project that is posted in the stream engine “getting started” section, and it works fine in a console app, but I am trying to make a C++ directX app and the syntax no longer works for these two callback functions

tobii_enumerate_local_device_urls(api, url_receiver, url);
tobii_gaze_point_subscribe(device, gaze_point_callback, 0);

if anyone knows a solution for this please let me know as I am really struggling to wrap my head around this
Thanks in advance

Ok so I have fixed the problem with function pointers by making the class functions static, all I need now is to be able to access the gaze point outside of these functions, which is difficult to do when they are static. Any tips?

Ok, I have actually managed to fix these issues, it turns out I was not initialising the static variables correctly. Now I can access the gaze point anywhere in the program
