Ok. Gabriele,
But I would like to know, how can I define DATATYPE on send and
recv? Could you give me an example?
For example, my class has the following design and I want to
send/recv Test object.
class Test {
private:
int coordinate;
vector<double> s;
public:
void setD(int, vector<double>);
double getParameter(int);
vector<double> getAll(void);
}
Thank you for all.
