vs2010 使用pthread进行多线程编程

来源：互联网发布：高帮男鞋知乎编辑：程序博客网时间：2024/06/16 09:49

1、从http://sourceware.org/pthreads-win32/下载pthread 的windows安装包，我下的是pthread-w32-2-9-1-release.zip，其他版本也可以。解压到pthread-w32-2-9-1-release。

2、打开vs2010，项目->属性->配置属性->VC++目录，包含目录里添加inlude路径，如下图所示，如果刚下载的压缩包放在D盘，则在包含目录那一栏添加：D:\pthread-w32-2-9-1-release\Pre-built.2\include;在库目录那一栏添加：D:\pthrea-w32-2-9-1-release\Pre-built2\lib

3、在链接器—>输入，附加依赖项一栏添加

pthreadVC2.lib;pthreadVCE2.lib;pthreadVSE2.lib;如下图所示。所有设置完成后点确定。

4、打开pthread-w32-2-9-1-release\Pre-built.2\lib\X86，将里面三个*.lib文件复制到你所建立的工程目录中去，这样就设置好了，大功告成。

如下一个简单的程序实例。

#include<stdio.h>#include<stdlib.h>#include<pthread.h>#define NUM_THREADS 4typedef struct{int threadId;}threadParm_t;void *threadFunc(void *parm){threadParm_t *p=(threadParm_t *)parm;fprintf(stdout,"Hello world from thread%d\n",p->threadId);pthread_exit((void *)&(p->threadId));return 0;}int main(int argc,char *argv[]){int i;int *res;res=(int *)malloc(sizeof(int));pthread_t thread[NUM_THREADS];threadParm_t threadParm[NUM_THREADS];for(i=0;i<NUM_THREADS;i++){threadParm[i].threadId=i;pthread_create(&thread[i],NULL,threadFunc,(void *)&threadParm[i]);}for(i=0;i<NUM_THREADS;i++){pthread_join(thread[i],(void **)&res);fprintf(stdout,"Thread %d has exited.\n",*res);}system("pause");return 0;}

运行程序得到如下结果。

如果运行时，提示缺少“pthreadVC2.dll”，将pthread目录下的pthreadVC2.dll文件拷贝到C:\Windows\System32（32位系统）中即可
