C # Multithreading practices-Lock and thread safety

, which will work, but only when all programmers agree to do so. While this is unreliable, locking a type is considered a very bad thing. For these reasons, static members on DateTime are thread-safe, a common pattern throughout the. NET framework-static members are thread-safe, while one instance member is not. From this mode you can also get some experience when writing custom types, do not create a problem that cannot be thread-safe!When it comes to writing common components, the good habit i

C + + Development: Why multithreading Read and write shared_ptr to lock the details _c language

I wrote in "Linux multithreaded Server programming: Using the Muduo C + + network Library" section 1.9, "re-discuss shared_ptr thread safety" in the article: (shared_ptr) The reference count itself is secure and unlocked, but the object's read-write is not because the shared_ptr has two data members and the read-write operation cannot be atomized. According to the documentation (http://www.boost.org/doc/libs/release/libs/smart_ptr/shared_ptr.htm#Thre

The reader thread can then acquire the lock without the writer having the l

C # WinForm Multithreading (i) Thread class library

Windows is a multitasking system, and if you are using Windows 2000 and later, you can view the programs and processes that are running on the current system through Task Manager. What is a process? When a program starts running, it is a process that refers to the memory and system resources that are used by the programs and programs that are running. And a process is composed of multiple threads, the thread is an execution flow in the program, each thread has its own proprietary registers (stac
