pthread mutex lock example

　　The Mutex (mutex) is the abbreviation for "Mutual exclusion". Mutexes are the primary way to implement thread synchronization and to protect simultaneous write-shared data.Mutex protection for shared data is like a lock. In Pthreads, only one

In gemfield's article "from pthread to qthread", we learned about the basic usage of threads, but most of the content was said to be discussed in this article, that is, thread synchronization. Gemfield has a metaphor in "from process to thread", so

Because pthread implements parallel computing based on shared memory, the use of shared variables in multiple threads has many synchronization problems. It may be okay to read the same variable in multiple threads, but it may cause inconsistency of

When we need to control access to shared resources, we can use a simple lock-up method to control. We can create a read / write program that shares a shared buffer and uses a mutex to control access to the buffer. 　The function pthread_mutex_init ()

Programming with pthread? What is pthread? Pthread, as the standard thread library for C/C ++ programming, is actually POSIX standard thread library.   So how to understand the POSIX standard? Below are links to some materials. If you are

Pthread is a set of user-level thread libraries, but kernel-level threads are used for implementation on Linux. The advantage is that the concurrency of programs can be fully improved, the thread can also call functions such as head as before,

Introduction POSIX thread is short for pthread, and POSIX thread isPOSIXStandard thread. This standard defines the internal API creation and thread manipulation.   Function The thread library implements the POSIX thread standard, usually
