_endthread, _endthreadex
Terminate a thread created by _beginthread or _beginthreadex, respectively.
void _endthread( void ); void _endthreadex( unsigned retval );
Parameter
- retval
- Thread exit code.
Remarks
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 to ensure proper recovery of resources allocated for the thread.
Note 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.
