Use conditional variables to improve efficiency This article is the last part of the POSIX thread trilogy series. Daniel will discuss in detail how to use conditional variables. The condition variable is a POSIX thread structure that enables you to "

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

A simple tool supporting Memory SharingPOSIX (interface with portable operating system) threads are a powerful means to improve code response and performance. In this series, Daniel Robbins precisely shows you how to use threads in programming. It

In Linux, the concept and processing of threads and processes are not strictly differentiated like other operating systems. in Linux, a thread is also called a lightweight process. in addition, the important difference between windows and Windows

Detailed description of condition Variables At the end of the previous article, I described a special problem: If the thread is waiting for a specific condition to happen, how should it handle this situation? It can repeatedly lock and unlock mutex

POSIX thread (pthread) programming defines a set of standard C programming language types, functions, and constants-And pthreads provides a powerful thread management tool. To make full use of pthreads, you must avoid common errors. A common error

Due to historical reasons, the2.5.x previous Linux did not provide kernel-level support for pthreads, so the pthreads implementation on Linux can only take the form of N:1, also known as the library implementation. Currently, Pthreads is

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.

I. POSIX thread attributes The POSIX thread library defines the thread attribute object pthread_attr_t, which encapsulates the thread attributes that can be accessed and modified by the thread creator. It mainly includes the following attributes: 1.

In the previous article, we talked about the thread code that causes exceptions. The two threads add one to the same global variable 20 times. The variable should be 40 at the end, but 21 at the end. What's going on? This problem occurs because one

Concepts and functions In a single-threaded program, we often use global variables to share data among multiple functions. In a multi-threaded environment, global variables are shared by all threads because data space is shared. However, sometimes

I. POSIX thread first-off functionPOSIX line Librariesthread-related functions form a complete series, and most functions have names that begin with "Pthread".To use these libraries, introduce header files The "-lpthread" option to use the compiler

The mutex is essentially a lock that provides protected access to the shared resource.1. Initialize:Under Linux, the mutex data type for a thread is pthread_mutex_t. Initialize it before use:For a statically allocated mutex, you can set it to

The POSIX thread library encapsulates a thread processing interface based on processor, operating system, and other features. For Linux systems based on the x86 processor architecture, it usually schedules a newly created thread to a core different
