  \class vpClient
  
  \ingroup Network

  \brief This class represents a Transmission Control Protocol (TCP) client.
  
  TCP provides reliable, ordered delivery of a stream of bytes from a program 
  on one computer to another program on another computer.

  Exemple of client's code, receiving and sending basic message
  It corresponds to the client used in the first exemple of vpServer class' documentation:
  
  \code
#include <visp/vpClient.h>
#include <iostream>

int main(int argc, char **argv)
{
  std::string servername = "localhost";
  unsigned int port = 35000;

  vpClient client;
  client.connectToHostname(servername, port);
  //client.connectToIP("127.0.0.1",port);

  int val = 0;

  while(1)
  {
    if(client.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;
    
    if(client.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;
  }
  
  return 0;
}
  \endcode
  
  Exemple of client's code, sending a vpImage on request form.
  It correspond to the server used in the second exemple of vpServer class' documentation.
  
  \code
#include <visp/vpClient.h>
#include <visp/vpV4l2Grabber.h>
#include <visp/vpImage.h>
#include <visp/vpDisplayX.h>
#include <visp/vpDisplayGDI.h>
#include <iostream>

#include "vpRequestImage.h" //See vpRequest class documentation

int main(int argc, char **argv)
{
#if defined(VISP_HAVE_V4L2)  
  std::string servername = "localhost";
  unsigned int port = 35000;
  
  vpImage<unsigned char> I; // Create a gray level image container
  
  // Create a grabber based on v4l2 third party lib (for usb cameras under Linux)
  vpV4l2Grabber g;
  g.setScale(1);
  g.setInput(0);
  g.open(I);

  // Create an image viewer
#if defined(VISP_HAVE_X11)
  vpDisplayX d(I, -1, -1, "Camera frame");
#elif defined(VISP_HAVE_GDI) //Win32
  vpDisplayGDI d(I, -1, -1, "Camera frame");
#endif

  vpClient client;
  client.connectToHostname(servername, port);
  //client.connectToIP("127.0.0.1",port);

  vpRequestImage reqImage(&I);

  while(1)
  {
    double t = vpTime::measureTimeMs();
    // Acquire a new image
    g.acquire(I);
    
    vpDisplay::display(I);
    vpDisplay::flush(I);
    
    client.sendAndEncodeRequest(reqImage);

    // A click in the viewer to exit
    if ( vpDisplay::getClick(I, false) )
      break;
  }

  return 0;
