返回信息流源程序如下
#include <windows.h>
#include <stdio.h>
DWORD WINAPI mythread(LPVOID para)
{
printf("Hello from the thread!\n");
return 0;
}
int main()
{
DWORD tid;
HANDLE hThread;
hThread = CreateThread(NULL, 0, mythread, NULL,0, &tid);
printf("Hello from the main program!\n");
WaitForSingleObject(hThread, INFINITE);
return 0;
}
为什么运行结果会是这样:
C:\program.exe
Hello from the main program!
Hello from the thread!
C:\program.exe
Hello from the main program!
Hello from the main program!
Hello from the thread!
Hello from the main program! 有时出现一次 有时出现两次.....

把CreateThread改成_beginthreadex
CreateThread没有为新线程建立tiddata结构，所以运行属于CRT函数的printf会产生Memory Leak。。。关于CreateThread和_beginthreadex的具体区别《Windows核心编程》里将的很清楚了。。。
