LINUX multi-thread design 1 IntroductionThe thread technology was proposed as early as 1960s, but the actual application of multithreading to the operating system was 80 years ago.In the middle of the year, Solaris was a leader in this field.

The biggest feature of threads is resource sharing, but the synchronization problem in resource sharing is the difficulty of multi-thread programming. In linux, multiple methods are provided to process thread synchronization. The biggest feature of

In order to effectively control the communication process between multiple processes and ensure the orderly and harmonious communication process, the OS must provide a synchronization mechanism to ensure effective collaboration between processes.

Multi-thread and synchronization in Linux and multi-thread synchronization in Linux Author: Vamei Source: http://www.cnblogs.com/vamei welcome reprint, please also keep this statement. Thank you!   A typical UNIX system supports multiple threads in

Process is in the system Program Basic Unit of execution and resource allocation. Each process has its own data segment, Code Segment and stack segment, which causes the process to have more responsible context switches and other actions during

Mutex lock for processing data of threads Mutex lock Mutex lock is used to ensure that only one thread is executing a piece of code within a period of time.The pthread_mutex_lock statement starts to lock with mutex lock. Subsequent code is locked

Mutex refers to mutually exclusive locks. It is a semaphores that are often used to prevent two processes or threads from accessing the same shared resources at the same time. 1. Data Type: In Linux, the thread mutex data type is pthread_mutex_t.

Yang Sha ZhouOctober 2001 This is a column about POSIX thread programming. On the basis of clarifying the concept, the author will detail the POSIX thread library API. This is the third article to introduce thread synchronization. I. mutex

Mutex lock Although the IPC semaphore mechanism can also be used in POSIX thread to implement mutex functions, the semphore function is obviously too powerful, the POSIX thread defines another set of mutex functions for thread synchronization. 1.

Summary of Linux multithreading and summary of linux multithreading A thread is the complete execution sequence of an independent task in a program, that is, a schedulable entity. A process is equivalent to an abstraction of a running program. Based

This article introduces the development process of DB2workload Based on Embedded SQL and C multi-thread, and provides a detailed list of program examples. This article provides an in-depth introduction to the multi-threaded C language and an

Reproduced http://blog.csdn.net/yusiguyuan/article/details/14161225   The synchronization technology between threads mainly focuses on mutex locks and condition variables. The combination of condition variables and mutex can well handle the

By default, readers in this article have already understood the basic concepts and functions of locks, mutex locks, and conditional variables in multithreading. This article only describes how to program calls in C ++. The mutex lock is very simple.

Introduction: The related functions are as follows:1 int pthread_cond_init (pthread_cond_t * cond, pthread_condattr_t * cond_attr );2 int pthread_cond_wait (pthread_cond_t * cond, pthread_mutex_t * mutex );3 int pthread_cond_timewait (pthread_cond_t

To allow data sharing between threads or processes, synchronization is usually required. Common Synchronization Methods include mutex lock, condition variable, read/write lock, and semaphore. In addition, synchronization between processes can also
