有关pthread线程的暂停与恢复的讨论

pthead线程的暂停与恢复的讨论，一个非常好的回答   http://bbs.csdn.net/topics/390321574   

希望对自己和有需要的朋友有很大的帮助。。。。

自己参考那个，选择和修改了那位兄弟的部分代码 ，，现在可以实现那个功能

void pthread_suspend(void)  
{  
	if (pthread_pause == false)  
	{  
		pthread_mutex_lock( &mutex_pause );  
		pthread_pause = true;  
		printf("\n------transport pause------\n");  
		pthread_mutex_unlock( &mutex_pause );      
	}  
	else  
	{  
		printf("the transport suspend already/n");  
	}  

}  
void pthread_resume(void)  
{   
	if (pthread_pause == true)  
	{  
		pthread_mutex_lock(&mutex_pause);  
		pthread_pause = false;  
		pthread_cond_broadcast(&cond_pause);  
		printf("------transport resume------/n");  
		pthread_mutex_unlock(&mutex_pause);   
	}  
	else  
	{  
		printf("transport resume already/n");  
	}  
} 

void* threadFunc(void* args)  //工作线程函数
{
   while(1)
   {
      if(!pthread_pause)
      {
                printf("working...");
          //work();
      }
      else
      {  
                printf("rest...");
      }
            sleep(1);
   }
   return ((void*)0);
}
void* threadFunc(void* args)  //工作线程函数 
{    
    while(1)    
    {       
        if(pthread_pause ＝＝ false)       
        {     work();       
        }       
        else      
        {             
           pthread_cond_wait(&cond_pause,&mutex_pause);
        }    
     }    
     return ((void*)0); 
}   


int main()
{
	pthread_t id;
	int ret;
	ret = pthread_create(&id,NULL,threadFunc,(void *)sockClient);
	if (ret != 0)
	{
		printf("Create thread error!\r\n");
		exit(1);
	}
     	pthread_create(&thread, NULL, threadFunc, NULL);
 
        while (1)
	{
		
			if( kbhit() )//有键盘输入 kbhit !0;
			{
				ch = getch();
				if( ch == 's' )
				{
					pthread_suspend();
				}
				if(ch == 'r')
				{
					pthread_resume();
				}
			}
			
	}
         return 0;
}
