Freetrack interface use in IL-2:CoD

[MadBlaster]

I'm not a programmer, but it looks like these are output variables for 6DoF:


if (getData(pData))
{
printf("Record ID: %d\n" , data.dataID);
printf("Yaw: %5.2f\n" , data.yaw );
printf("Pitch: %5.2f\n" , data.pitch );
printf("Roll: %5.2f\n" , data.roll );
printf("X: %5.2f\n" , data.x );
printf("Y: %5.2f\n" , data.y );
printf("Z: %5.2f\n" , data.z );
}
else
{
printf("Nothing returned from getData\n");
break;
}
}


Why can't CoD hook off that? I guess it is "C" language format.
