windows多线程编程_python的优点_windows多线程编程实例(6)

第二个demo.

/*******************************************************

*

* deom2---四个线程同时写一个文件( 有参数 )

*

***********************************************************/

＃i nclude <windows.h>

＃i nclude <process.h> /* _beginthread, _endthread */

＃i nclude <iostream>

＃i nclude <fstream>

＃i nclude <string>

using namespace std;
