Question: I recently read the source code of memcached and intend to write my learning history. It is also because it is the first time that I officially contacted memcached. I hope you can talk more about it. This series of articles divides

Summary: overlapped I/O, also known as asynchronous I/O, is an asynchronous I/O model. Asynchronous I/O is different from Synchronous I/O, Program Suspended until I/O processing is complete. Asynchronous I/O: calls a function to tell the OS to

has been engaged for a long time, the producer and consumer model strengthened version (multi-person production multi-person consumption).The previous code format is no longer a slot (try to improve later)The output is an infinite loopImport

Recently reviewed the thread, found running consumer and producer code parts, there will always be first consumption after production. The source code is as follows: public class Producerconsumer {public static void main (string[] args) {syncstack

A, process and thread 1. What is the process? Narrowly defined: Processes are instances of running programs (an instance of the a computer program, is being executed). Generalized definition: A process is a program with a certain number of

In software development, multithreaded programming technology is widely used, I believe that the multi-threaded task is no longer unfamiliar to us. With multithreading, we can do multiple things, rather than one task at a to do. For example:

I. Definition of deadlockmultithreading and multi-processes improve the utilization of system resources and improve the processing power of the system. However, concurrent execution also brings new problems-deadlocks. A deadlock is a deadlock

Thread Synchronization is a means to ensure secure access to competing resources by multiple threads.Thread Synchronization is a difficult issue in Java multi-thread programming. Developers often don't know what is competing resources, when

Explore the Async and Await analysis of c #Async and Await are newly added asynchronous programming methods in net4.x. The objective of Async and Await is to simplify asynchronous programming. The following is a simple comparison with the previous

The second method is undoubtedly much easier than the first method. We only need to add the new compilation parameter-g3 to the global Makefile to support debugging of all macros in the entire project code. Of course, this method also has a

GDB for MultithreadingProgramDebugging supports the following: Thread-generated notification: when a new thread is generated, GDB will provide a prompt. (GDB) rStarting program:/root/thread[New thread 1073951360 (lwp 12900)][New thread

Programmers have always argued that _ beginthread or createthread should be used in Windows programs to create threads. This article will discuss this issue from the source code of the CRT. I. Cause Today, a friend asked me whether _ beginthread or

Createthread is a win 32api function, and _ beginthread is a CRT (C Run-Time) function. They are all functions created to implement multiline city, and they have the same usage method, the same parameter list. But what are their differences? In

Summary of multi-threaded program debugging using gdb and summary of multi-threaded program debugging using gdbGo to: Summary of using gdb to debug multi-threaded programs I have never had much access to GDB multi-threaded debugging. Recently, I

Each dll can have an entry point function dllmain, which will be called at different times. The following is the general form of dllmain: Bool winapi dllmain (hinstance hinstdll, // handle to DLL module DWORD fdwreason, // reason for calling

In some cases deadlocks can be avoided. This article shows three techniques for avoiding deadlocks: Lock order Lock time limit Deadlock detection Lock orderDeadlocks can easily occur when multiple threads require the same locks,

When there are multiple threads in a process and it is possible to access the same resource at this point, security issues may occur, so you need to place these resources in a synchronized code block or in a synchronization method before you access
