Socket network programming first, socket first
First, I would like to summarize some of the books required for job interviews: I suddenly felt very steadfast in my mind, "the beauty of programming", "The sword refers to offer", "Unix environment programming", "Unix network programming", and "POSIX multi-thread programming, I am no longer confused. I finally know what I can do after I graduated from the comp

Today, qtcreator is installed in Ubuntu to test whether it can be used. As a result, a problem occurs during the test. After a simple compilation, F5 compilation appears in gnome-terminal. Cannot connect creator comm socket/tmp/qt_temp.u14973/stub-socket: no such file or directory So I checked that QT cannot be executed using gnome-terminal, and X-team is required. So I thought of the solution: Find tool

Python Network toolkit twisted Matrix
Twisted matrix is an increasingly popular pure Python framework for programming network services and applications. Although twisted matrix has a large number of loosely coupled modular components, the central concept of the framework is the idea of non-blocking asynchronous servers. In thi

Alarm (5);
int ret = read (FD, buf, sizeof (BUF));

Program general framework as shown above, if read in the 5s by the SIGALRM signal interruption and return, it indicates a timeout, otherwise no timeout has been read to the data, cancel the alarm clock. However, this method is not commonly u
First, socketIn general, the socket has an alias called a socket.Sockets originate from UNIX and can be manipulated using "open open–> read-write write/read–> close" mode. Socket is an implementation of this pattern, the socket is a special kind of file, some of the socket function is to do it (read/write IO, open, clo

process number 5, and the number 5th process can exist in machine B, so the phrase "process 5th" is meaningless. Second, the operating system supports a large number of network protocols, different protocols work in different ways, address format is also different. Therefore, the inter-network process communication also solves the problem of multi-protocol recognition.
In fact, the TCP/IP protocol family has helped us solve this problem, the network layer "IP address " can uniquely identify the
