Overview

st_asio_wrapper is an asynchronous c/s framework based on Boost.Asio, besides all benefits brought by Boost and Boost.Asio, it also contain:

1. Based on message just like UDP with several couple of build-in packer and unpacker;
   
2. Support packer and unpacker customization, and replacing packer and unpacker at run-time;
   
3. Automatically reconnect to the server after link broken;
   
4. Widely support timers;
   
5. Support object pool, object reusing;
   
6. Support message buffer;
   
7. Support ssl;
   
8. Support TCP/UDP.
   Quick start:

###server: Derive your own socket from st_server_socket, you must at least re-write the on_msg or on_msg_handle virtual function and handle messages in it;
Create a st_service_pump object, create a st_server object, call st_service_pump::start_service;
Call st_server_socket::send_msg when you have messages need to send.
###client: Derive your own socket from st_connector, you must at least re-write the on_msg or on_msg_handle virtual function and handle messages in it;
Create a st_service_pump object, create a st_tcp_client object, set server address via st_connector::set_server_addr, call st_service_pump::start_service;
Call st_connector::send_msg when you have messages need to send.
Directory structure:

Directory compatible_edition has the same structure as st_asio_wrapper, it is so called compatible edition, because it doesn't used any C++0x features, so it can be compiled by old compilers which don't support C++0x.
All source codes are placed in directory include, other directories hold demos (except compatible_edition).
Demos:

###asio_server: Demonstrate how to implement tcp servers, it cantains two servers, one is the simplest server (normal server), which just send characters from keyboard to all asio_clients, and receive messages from all asio_clients (then display them); the other is echo server, which send every received message from test_clients back.
###asio_client: Demonstrate how to implement tcp client, it simply send characters from keyboard to asio_server, and receive messages from asio_server (then display them).
###test_client: Used to test the performance of echo server.
###file_server: A file transfer server.
###file_client: A file transfer client, use get <file name1> [file name2] [...] to fetch files from file_server.
###udp_client: Demonstrate how to implement UDP communication.
###ssl_test: Demonstrate how to implement TCP communication with ssl.
Compiler requirement:

Normal edition need Visual C++ 10.0, GCC 4.6 or Clang 3.1 at least;
Compatible edition does not have any limitations, just need you to compile boost successfully.
Boost requirement:

1.49 or highter, earlier edition maybe can work, but I'm not sure.
