KINOVAAPIUSBCOMMANDLAYER_API int GetGlobalTrajectoryInfo ( TrajectoryFIFO Response)

This function returns informations about the trajectories FIFO stored inside the robotical arm.

Parameters:
ResponseThe structure containing the FIFO's informations
#include <iostream>
#include <dlfcn.h> //Ubuntu
#include <vector>
#include "KinovaTypes.h"
//Note that under windows, you may/will have to perform other #include
