Shouldn't it be _endthreadex instead of _exitthreadex?

_endthreadex terminates the thread that is calling _endthreadex. You should call it in thrFunc() to terminate it.

ok i figured that, but is there no way to terminate it from the
outside?

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

TerminateThread() would help, if you are using windows (i assume that because of
_beginthread ... and so on). But it is clearly stated in the docs that this command should
be used only under extreme circumstances. The clean way would be to implement an
'HEVENT' (CreateEvent()), checking if it is signaled and if yes terminated the thread from
inside.
If you are using MFC, another possibility is using a CWinThread, which has a own message
loop - using PostThreadMessage() you can send a stop message and its handler then
calls the _exitthread() function.

Hello!
Your code will work so:
startThread(){
 handle=_beginthreadex(thrFunc, ....);
 /* store handle wherever */
}
stopThread(){
_endthreadex(handle);
}
