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
POSIX Threading (i): Threading model, Pthread series functions, and simple multithreaded server-side programsOne, the thread has 3 kinds of models, namely N:1 user threading model, 1:1 core threading model and N:M hybrid threading model, POSIX
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
The previous understanding of the property object pthread_attr_t is very simple. I have found some useful information from the Internet.
_ Detachstate indicates whether the new thread is out of sync with other threads in the process. If it is set
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
When using GCC to compile and use POSIX thread programs, additional options are often required to use the thread-safe Library and header files, in some old books, you can simply add the link option-lpthread, as shown in the following code:Shell code
1. Pthread Thread Concept
The multithreading under Linux system follows the POSIX thread interface, called Pthread. Write a multithreaded program under Linux, you need to use the header file Pthread.h, the connection needs to use the library
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,
The correct usage of conditional variables in Linux c multi-line libraries PthreadMultithreaded C language Linuxsemaphore condition variables(This article's reader orientation is to understand the Pthread common multithreaded API and Pthread mutex,
In Unix programming, learning to use fork and signal is quite basic.
Fork () and signal are often used in daemon resident programs, such as a4c. tty, yact, and chdrv are also useful for most large programs, such as Mozilla, Apache, and
