/*************************************** **************************************** **
Bool getexltcodethread (
Handle hthread,
Lpdword lpexitcode
);
Handle Of The hthread returned by createthread ()
Lpexitcode points to DWORD to accept the end code
Return Value:
If the request is successful, true is returned. Otherwise, false is returned. getlasterror () is called to identify the cause.
If the thread has ended, the end code is included in the lpexitcode parameter.
If the thread has not ended, the value brought back by lpexitcode is still_active.
