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 <visp/vpServer.h>
#include <iostream>
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)
{
if(serv.receive(&val) != sizeof(int)) //Receiving a value from the first client
std::cout << "Error while receiving" << std::endl;
else
std::cout << "Received : " << val << std::endl;
val = val+1;
if(serv.send(&val) != sizeof(int)) //Sending the new value to the first client
std::cout << "Error while sending" << std::endl;
else
std::cout << "Sending : " << val << std::endl;
}
}
return 0;
}

Exemple of server's code, receiving a vpImage on request form. It correspond to the client used in the second exemple of vpClient class' documentation.

#include <visp/vpServer.h>
#include <visp/vpDisplayX.h>
#include <visp/vpDisplayGDI.h>
#include "vpRequestImage.h" //See vpRequest class documentation
int main(int argc,const char** argv)
{
int port = 35000;
std::cout << "Port: " << port << std::endl;
vpServer serv(port);
serv.start();
#if defined(VISP_HAVE_X11)
vpDisplayX display;
#elif defined(VISP_HAVE_GDI) //Win32
vpDisplayGDI display;
#endif
vpRequestImage reqImage(&I);
serv.addDecodingRequest(&reqImage);
bool run = true;
while(run){
serv.checkForConnections();
if(serv.getNumberOfClients() > 0)
{
int index = serv.receiveAndDecodeRequestOnce();
std::string id = serv.getRequestIdFromIndex(index);
if(id == reqImage.getId())
{
#if defined(VISP_HAVE_X11) || defined(VISP_HAVE_GDI)
if (! display.isInitialised() )
display.init(I, -1, -1, "Remote display");
#endif
// A click in the viewer to exit
if ( vpDisplay::getClick(I, false) )
run = false;
}
}
}
return 0;
