Generally, most of the types we create for receiving errors are declared as follows:
boost::system::error_code error
We use this type to accept Errors generated in functions, such:
socket.connect(endpoint, error);
If the connection fails, the error type will be saved to error. For example, if the connection to the host fails, this error may be returned.
boost::asio::error::host_not_found;

ServerCodeThe function and bind dependent on boost are used for callback. This type of down Machine occurs during asynchronous calls. Let's talk less about the Code:
VoidFN (STD ::StringStr );Char* Temp_str =New Char[24]; Strcpy (temp_str,"1212");Boost: function f=Boost: BIND (FN, temp_str );F ();
The f function object here stores a temp_str pointer. If it is
, which ensures that it is initialized during compilation rather than runtime. So there is no problem with multiple threads initializing it at the same time. The Boost line threading provides boost::call_once to support "one implementation" and defines a flag Boost::once_flag and a macro boost_once_init that initializes the flag. List6 is an example of using
It has been several years since I started to get started with boost, but it is hard to get familiar with it. The analysis of some of its source code is also a bit of water. Have time to sort it out.1. Overview

There is always a saying that to become a master, you must read more highly handwritten source code. Which codes are good materials? C ++ standard library source code? No, if you have read it, you will find that either a variety of expressions that are unique to implementation are confusing, or a horrible code style (such as an underline everywhere) is uncomfortable. The Boost library code is quite clear, reasonable comments, and naming con

What is boost
The boost library is an open-source and free third-party library. It is a very good library and one of the best practices of the C ++ standard. Therefore, it is often used for commercial development. Therefore, if you are engaged in C ++ and have
Boost. Asio c ++ network programming translation (24), boost. asio Network ProgrammingMultithreading In the Asynchronous Server I have displayed on the client and the server in Chapter 4th. The Asynchronous Server is single-threaded, and all things happen in main:

situation, to achieve backward compatibility of all previous versions, to achieve smooth forward upgrade function. In the network by server and client design, the server is often designed to consider the upgrade time is relatively long, and the client is ready to be replaced or upgraded. This causes the server to be compatible with different versions in order to accommodate different user requirements. For example, the current mobile system updates v

TCP: resolver is generally used in combination with TCP: resolver: Query. You can use the word "query" to obtain the corresponding information of the socket, generally, we care about the address and port of socket. through TCP: resolver, it is easy to set and query. It uses query to set the IP address in string format, such as 192.168.0.200 or the Host Name HTTP: // The localhost and port "8080" are converted into the internal representation format of the socket, so that we can directly use the
