How to use

This demo can run with local host or 2 device have connection through internet

• server.cpp
  • read message from client and write message to client
• clent.cpp
  • read message from server and write data to server
• ioservice1
  • test async_wait with multil thread

Build:

g++ server.cpp -o server -lpthread
g++ client.cpp -o client -lpthread
g++ thread.cpp -o thread -lpthread

Run:

./server
open other terminal
./client

Explain

Client

tcp::resolver::query q{"127.0.0.1", "2014"};
resolv.async_resolve(q, resolve_handler);
ioservice.run();

Handler

• resolve_handler: call asyn_connect()
• connect handler: call async_read(), async_write(), write()
• read_handler: cout.write <<

Variables:

• io_service ioservice;
• tcp::resolver resolv{ioservice};
• tcp::socket tcp_socket{ioservice};

Server

• tcp_acceptor.listen();
• tcp_acceptor.async_accept(tcp_socket, accept_handler);
• ioservice.run();

Handler

• accept_handler: call async_read(), async_write()
• read_handler: cout.write <<

Variables:

• io_service ioservice;
• tcp::endpoint tcp_endpoint{tcp::v4(), 2014};
• tcp::acceptor tcp_acceptor{ioservice, tcp_endpoint};
• tcp::socket tcp_socket{ioservice};
