两个测试程序

 

本来是想测试一下在多线程环境下printf多次输出的情况，验证一下自己的想法，结果自己的测试程序貌似有问题，测试不出来.....先记下如何创建线程，减少烦人的编译错误先

 

/*	-----------------------------------------------------------------------------------
	这个是用_beginthreadex创建线程的。

//#define   _WIN32_WINNT   0x0400 

#include<windowsx.h>//里面竟然不包括windows.h
#include<windows.h> //为什么不支持Windowsx.h
#include<stdio.h>
#include<process.h>
