了解MSDN _beginthreadex函数示例
_beginthreadex MSDN 上有此函数page：
unsigned __stdcall SecondThreadFunc( void* pArguments )
{
printf( "In second thread...\n" );
while ( Counter < 1000000 )
Counter++;
_endthreadex( 0 );
return 0;
}
我知道可以用函数GetExitCodeThread获取_endthreadex返回的值，但是如何获取return返回的值代码>?
另一个问题：_endthreadex 不是结束线程吗，为什么他们在后面放了一个return 0？
There's this function on _beginthreadex MSDN page:
unsigned __stdcall SecondThreadFunc( void* pArguments )
{
printf( "In second thread...\n" );
while ( Counter < 1000000 )
Counter++;
_endthreadex( 0 );
return 0;
}
I know you can get the value returned by _endthreadex with the function GetExitCodeThread, but how do you get the value returned by return?
Another question: doesn't _endthreadex end the thread, why did they put a return 0 after that?

在此代码片段中，
return语句确实只是为了让编译器满意。然而，事实上，您不需要调用_endthreadex，因为它是在您从线程函数返回后由_beginthreadex在内部调用的。它将您的返回值传递给_endthreadex（或从中传递给ExitThread）。请参阅Raymond Chen 的文章
In this snippet the
returnstatement is indeed only to make the compiler happy. However, in fact, you don't need to call_endthreadexas it is called internally by_beginthreadexafter you return from your thread function. And it passes your return value to_endthreadex(orExitThread, from it).See Raymond Chen's article
return 0只是为了让编译器满意。_endthreadex不返回。return 0is there just to make the compiler happy._endthreadexdoes not return.
