今天把APUE翻出来看看 那五个函数的实现可以作为学习的好例子TELL_WAIT TELL_PARENT TELL_CHILD WAIT_PARENT WAIT_CHILD1.用signal实现#include "apue.h"static int pdf1[1],pfd2[2];void TELL_WAIT(void){ if(pipe(pfd1)<0 || p

创建线程int pthread_create(pthread_t *thread,pthread_attr_t *attr,void *(*start_routine)(void *),void *arg);return 0 on success,an error number if anything goes wrong结束线程void pthread_exit(void * r

 Pipe：connecting a data flow from one process to another进程管道：Process PipesFILE * popen(const char command,const char *open_mode);command：the name of the program to runopen_mode:must be "r" or

Starting New Processint system(const char * string);等同于sh -c string  用exec函数族Replacing a Process Imageexec函数族replaces the current process with a new process specified by the path or file

Semaphore: for managing access to resourcesShared memory:for highly efficient data sharing between programsMessaging:for an easy way of passing data between programs 1.Semaphores一般来说一个thread

下面的例子都在Ubuntu8.04 GCC下编译的结果，有些没有给结果编程一定要自己动手试一试！1.定义与声明，定义要分配内存，声明只是声明在别处定义了int a;     //定义extern int a;  //声明 char str[100]extern char str[]  //ok char * str[]extern char str[]

Linux下通用线程池的创建与使用本文给出了一个通用的线程池框架，该框架将与线程执行相关的任务进行了高层次的抽象，使之与具体的执行任务无关。另外该线程池具有动态伸缩性，它能根据执行任务的轻重自动调整线程池中线程的数量。文章的最后，我们给出一个简单示例程序，通过该示例程序，我们会发现，通过该线程池框架执行多线程任务是多么的简单。 为
