how to send classes defined in .proto (protocol-buffers) over a socket
- by make
Hi,
I am trying to send a proto over a socket, but i am getting segmentation error. Could someone please help and tell me what is wrong with this example?
file.proto
message data{
required string x1 = 1;
required uint32 x2 = 2;
required float x3 = 3;
}
client.cpp
...
// class defined in proto
data data_snd;
data data_rec;
char *y1 = "operation1";
uint32_t y2 = 123 ;
float y3 = 3.14;
// assigning data to send()
data_snd.set_x1(y1);
data_snd.set_x2(y2);
data_snd.set_x3(y3);
//sending data to the server
if (send(socket, &data_snd, sizeof(data_snd), 0) < 0) {
cerr << "send() failed" ;
exit(1);
}
//receiving data from the client
if (recv(socket, &data_rec, sizeof(data_rec), 0) < 0) {
cerr << "recv() failed";
exit(1);
}
//printing received data
cout << data_rec.x1() << "\n";
cout << data_rec.x2() << "\n";
cout << data_rec.x3() << "\n";
...
server.cpp
...
//receiving data from the client
if (recv(socket, &data_rec, sizeof(data_rec), 0) < 0) {
cerr << "recv() failed";
exit(1);
}
//printing received data
cout << data_rec.x1() << "\n";
cout << data_rec.x2() << "\n";
cout << data_rec.x3() << "\n";
// assigning data to send()
data_snd.set_x1(data_rec.x1());
data_snd.set_x2(data_rec.x2());
data_snd.set_x3(data_rec.x3());
//sending data to the server
if (send(socket, &data_snd, sizeof(data_snd), 0) < 0) {
cerr << "send() failed" ;
exit(1);
}
...
Thanks for help and replies-
