Detailed Description

This class represents a Transmission Control Protocol (TCP) server.

TCP provides reliable, ordered delivery of a stream of bytes from a program on one computer to another program on another computer.

Exemple of server's code, receiving and sending basic message. It corresponds to the client used in the first exemple of vpClient class' documentation.

#include <iostream>
#include <visp3/core/vpServer.h>
int main(int argc,const char** argv)
{
int port = 35000;
vpServer serv(port); //Launch the server on localhost
serv.start();
bool run = true;
int val;
while(run){
serv.checkForConnections();
if(serv.getNumberOfClients() > 0)
{
// Receiving a value from the first client
if(serv.receive(&val) != sizeof(int))
std::cout << "Error while receiving" << std::endl;
else
std::cout << "Received : " << val << std::endl;
val = val+1;
// Sending the new value to the first client
if(serv.send(&val) != sizeof(int))
std::cout << "Error while sending" << std::endl;
else
std::cout << "Sending : " << val << std::endl;
}
}
return 0;
}
This class represents a Transmission Control Protocol (TCP) server.
