Python has many advantages to facilitate the technical aspects of computer applications. However, people who really know the Python programming language are not the majority, the following is an introduction to the Python programming language. In the first step, if you are just beginning to understand the Python programming language, you now need a set of Python

As a developer, we really need to learn so many new programming languages. The choices we have now are quite rich, with command languages, functional languages, object-oriented languages, dynamic languages, compiled languages, interpreted languages, and scripting languages, among other things. These programming languages, which are in the forefront of the industry, provide a unique analytical perspective fo

This article is based on the embedded IoT Development Engineer's vision of network programming and web programming. This article may be a little easier for children's shoes that focus on the development of the Java back-end service. But network programming and web programming are a vacuum for most embedded IoT engineer

Theoretical basis Stream: Call fopen Open file after file read and write operation will create a stream, socket network communication will also create a flow, the flow is a data transmission for the purpose of a bridge, in fact, refers to the flow of data, we can understand the data sent and received the path. I/O stream separation: refers to the transmission of data and receive streams separately, controlled by 2 different objects instead of 1 objects. We've talked about 2 I/O flow

Introduction to the design of non-blocking methodsThe most significant difference between the non-blocking operation and the blocking mode is that the function's call returns immediately, regardless of whether the data was successfully read or successfully written. You can do non-blocking programming by using FCNTL () to set the socket file descriptor following code:Fcntl (S, F_SETFL, O_nonblock);where S is the socket file descriptor, using the F_SETF

is a generic socket programming diagram .Establishment of the server:Gets the native name used to parse the IP address of the machine, then the IP address is successfully bound, then the server is listening, waiting for the client to connect. That is, the next step is the TCP/IP three handshake operation, the operation succeeds the server and the client can communicate. Here is the comment code:1 voidSocketconnect ()2 {3 Charserver_name[ -];4 wsad

icloud document storage programming is more complex relative to key value data stores, involving customizing document classes, obtaining icloud document catalogs, locating documents in ubiquity containers, saving documents, and resolving document conflicts. Example: icloud document storage Programming design Example describes the icloud document storage programming
