fork()函数,Linux系统调用 头文件: #include 函数定义: int fork( void ); 返回值: 子进程中返回0,父进程中返回子进程ID,出错返回-1 函数说明: 一个现有进程可以调用fork函数创建一个新进程。由fork创建的新进程被称为子进程(child process)。fork函数被调用一次但返回两次。两次返回的唯一区别是子进程中返回0值而父进程中返回子进程ID。 子进程是父进程的副本,它将获得父进程数据...
A thread may be created as a joinable thread (the default) or as a detached thread. A joinable thread, like a process, is not automatically cleaned up by GNU/Linux when it terminates. Instead, the thread's exit state hangs around in the system (kind of like a zombie process) until another thread calls pthread_join to obtain its return value. Only then are its resources released. A detached thread,...

I have written a program with two threads. but it has some errors.[code]

thread Lifecycle:A new threads are created with thread.new. You can also use the synonyms thread.start and thread.fork. There is no need to start a thread after creating it, it begins running automatically when CPU resources become available. The thread class defines a number of methods to query and manipulatethe thread while it is running. A thread runs the code in the blockassociated with the c...
POSIX thread 一 概述 Pthread是一套通用的线程库, 它广泛的被各种Unix所支持, 是由POSIX提出的. 因此, 它具有很好的可移植性. 例1: /**/ #include pthread.h> void *pp(void *arg) { while (1) { ...

有人在windows下用过这个模块吗?为什么用threds模块可以实现多线程,但使用use thread;就总是报错!下面是用thread::Pool模块时报的错: Undefined subroutine &threads::new call at C:/Perl/site/lib/thread/Pool.pl line 110 我也单独试了,用thread模块,启动不了多线程!麻烦大家给分析一下!下面是thread模块的一个小例子,大家看看哪里错了! #!c:\perl\bin\perl -w use thread; my @threads; my @info; $info[0]="1";...
