Thread considerations
How the thread ends ：
1 Thread functions return This is a normal exit
2 ExitThread
This function will terminate the thread , And causes the operating system to clear all operating system resources used by the thread . however ,C++ resources （ Such as C++ Class object ） Will not be revoked . For this reason , It's best to return... From a thread function , Instead of calling ExitThread Come back to .
Of course , have access to ExitThread Of dwExitThread Parameter tells the system why to set the exit code of the thread .ExitThread The function does not return any value , Because the thread has terminated , Can't execute more code .
3 TerminateThread
This kind of situation , Do not release the stack resources of the thread
4 The process exited .
