Making A simple TCP Client:

Includes

#include <iostream>
#include <string>
#include "Socket.hpp"

Setting up host

int main() {
  if(argc < 3) {
    std::cerr << "Usage: " << argv[0] << "  [hostname] [port]" << std::endl;
    return EXIT_FAILURE;
  }
  const std::vector<uint8_t> msg = {'H','e','l','l','o',' ','W','o','r','l','d'};
  const std::string host = argv[1];
  
  
  cppsocket::Network network;  
  cppsocket::Socket client(network);
  
  client.setBlocking(false);
  client.setConnectTimeout(2.0f);

Connect to server and set up callback functions

  client.connect(host);
  
  client.setReadCallback([](const cppsocket::Socket& server, const std::vector<uint8_t> data){
    std::cout <<
       "Recieved data: " << data.data() << " from: " << cppsocket::ipToString(server.getRemoteIPAddress())
    << std::endl;
  });
  
  client.setConnectCallback([](cppsocket::Socket& server) {
    std::cout << "Connected to " << cppsocket::ipToString(server.getRemoteIPAddress()) << std::endl;
    server.send(msg);
  });
  
    client.setConnectErrorCallback([&client, address](cppsocket::Socket& server) {
      std::cout << "Failed to connected to " << cppsocket::ipToString(server.getRemoteIPAddress()) << std::endl;
      client.connect(host);
   });

Updating

  const std::chrono::microseconds sleepTime(10000);

  for (;;)
  {
      network.update(); // call main server loop and check for connections

      std::this_thread::sleep_for(sleepTime);
  }  
}
