Network Programming in Linux: time_wait status The last time_wait status was not very understandable when I started to look at the TCP socket's 4-way handshake termination flowchart. looking back, I found that the time_wait status is very delicate. there are two reasons for designing the time_wait status: The TCP full-duplex connection can

In one of the basics of Linux network programming, we talk about the connection and difference between the stream socket and the datagram socket. Let's briefly talk about UDP-based network programming.Two common functionsInt recvfrom (int sockfd, void * buf, int len, unsigned int flags, struct sockaddr * from int * fro

If you are familiar with network programming on Windows, it is very easy to transfer network programming to Linux. Because they all use socket APIs for programming. The following sample code demonstrates a simple server program. T

Write data to file: 4, read the data in the file: Note: ssize_t = signed int, size_t = unsigned int, are aliases declared by TypeDef for basic data types. Now that you have the basic data type, why do you need to alias it? Because int is currently considered to be 32-bit, and in the past 16-bit OS age, int is 16-bit. depending on

After all, the timeout is to not let your program wait there for a time to return.2) Even if the wait timeout value is not reached, but the other party has closed the socket, then recv () will immediately return and receive how much data is returned.2 Project Problem descriptionThe client needs to go to the server every minute to

This is because multiple threads share the Epoll descriptor, and several epoll functions Epoll_ctl, epoll_wait, and so on are thread-safe, so you can reuse a Epoll descriptor in multiple threads.Here is a reference code written by a foreigner:　　/** Copyright (C) 2012-2014 www.56.com Email:jingchun.zhang at renren-inc.com; Jczhang at 126.com; Danezhang77 at gmail.com* * 56VFS is copied only under the terms of the GNU general public License v3*/#include "vfs_s O.h "#include" vfs_in
