CRITICAL_SECTION的使用例子

#include "stdafx.h"
#include <WinSock2.h>//内包含CRITICAL_SECTION
#include <list>
#include <process.h>
using namespace std;
CRITICAL_SECTION g_cs; 
list<int> int_list;
unsigned int __stdcall read_thread(void *p)
{
	for(;;)
	{
		EnterCriticalSection(&g_cs);
		list<int>::iterator iter;
		for(iter = int_list.begin(); iter != int_list.end() ;iter++)
		{
			printf("%d\n",*iter);
		}
		LeaveCriticalSection(&g_cs);	
		if(int_list.size() == 0) break;
		printf("\\\\\\\\\\\\\\\n");
		Sleep(500);//控制显示间隔时间，去掉可以更能看出效果
	}

	return 1;
}
unsigned int __stdcall delete_thread(void *p)
{
	for(;;)
	{
		EnterCriticalSection(&g_cs);
		list<int>::iterator iter;
		if(int_list.size() == 0){printf("清空完毕！\n");break;}
		for(iter = int_list.begin(); iter != int_list.end() ;iter++)
		{
			int_list.erase(iter);
			break;
		}
		LeaveCriticalSection(&g_cs);
		Sleep(1000);
	}
	
	return 1;
}
int _tmain(int argc, _TCHAR* argv[])
{

for(int i = 0; i != 10 ; ++i)
	int_list.push_back(i);
