Terminates a thread; _endthread terminates a thread that's created by _beginthread and _endthreadex terminates a thread that's created by _beginthreadex.
void _endthread( void ); void _endthreadex( unsigned retval );
Thread exit code.
You can call _endthread or _endthreadex explicitly to terminate a thread; however, _endthread or _endthreadex is called automatically when the thread returns from the routine passed as a parameter to _beginthread or _beginthreadex. Terminating a thread with a call to endthread or _endthreadex helps ensure proper recovery of resources allocated for the thread.
For an executable file linked with Libcmt.lib, do not call the Win32 ExitThread API; this prevents the run-time system from reclaiming allocated resources. _endthread and _endthreadex reclaim allocated thread resources and then call ExitThread.
_endthread automatically closes the thread handle. (This behavior differs from the Win32 ExitThread API.) Therefore, when you use _beginthread and _endthread, do not explicitly close the thread handle by calling the Win32 CloseHandle API.
Like the Win32 ExitThread API, _endthreadex does not close the thread handle. Therefore, when you use _beginthreadex and _endthreadex, you must close the thread handle by calling the Win32 CloseHandle API.
_endthread and _endthreadex cause C++ destructors pending in the thread not to be called.
