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.

Example of server's code, receiving and sending basic message. It corresponds to the client used in the first example 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;
}

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

#include <visp3/core/vpServer.h>
#include <visp3/gui/vpDisplayGDI.h>
#include <visp3/gui/vpDisplayX.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
 
  vpImage<unsigned char> I;
 
  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
 
        vpDisplay::display(I) ;
        vpDisplay::flush(I);
 
        // A click in the viewer to exit
        if ( vpDisplay::getClick(I, false) )
          run = false;
      }
    }
