C语言使用pthread多线程编程(windows系统)一

运行之前需要做一些配置： 
1.下载PTHREAD的WINDOWS开发包 pthreads-w32-2-4-0-release.exe（任何一个版本均可） 
   http://sourceware.org/pthreads-win32/ ，解压到一个目录。 
2.找到include和lib文件夹，下面分别把它们添加到VC++6.0的头文件路径和静态链接库路径下面： 
   a).Tools->Options，选择Directory页面，然后在Show directories for:中选择Include files(默认)     在Directories中添加include的路径。在Show directories for:中选择Library files， 
    在Directories中添加lib的路径。 
   b).Project->Settings,选择Link页面，然后将lib下的*.lib文件添加到Object/library Modules, 
     各lib文件以空格隔开。 
   c).将lib下的*.dll文件复制到工程目录下，即根目录。  

3.C代码 :

#include <stdio.h>  
#include <stdlib.h>  
#include <pthread.h>  
#include <windows.h>  
  
int  piao = 100;  
  
pthread_mutex_t mut;  
   
void* tprocess1(void* args){  
   int a = 0;  
       while(true){  
           pthread_mutex_lock(&mut);  
           if(piao>0){  
            Sleep(1);  
            piao--;  
            printf("窗口1----------------还剩%d张票
",piao);  
           }else{  
            a = 1;  
           }  
          pthread_mutex_unlock(&mut);
