There is no exception management in the function. Its code based on C and
migrated to C++. I can wrapper it with try catch.

Is that function exception-safe?

I can't change the function so it will check the token, that is my main
problem. I want to be able to stop the execution from outside the function.

 

Thank you anyway,

Vadim.

I would suggest to introduce a Cancellation Token as parameter to both
functions. If one function becomes ready it sets the cancelation flag to
true, so that other function can check it and exit. In the most simple case
it can be a volatile boolean value passed by reference to both functions.

 

 

Hope that helps,

Ovanes

Hello,

I have a problem with interruption of threads.
I have one function that I want to run in two different threads with
different parameters. When one of the function's instances finishes it stops
the other instance. I can't change the function's code, but I can write
wrapper to it. 
My problem is in stopping the other thread. Using timed_join I find which
thread is finished, but I can't find a good solution for stopping the second
one.
How should I use interrupt method correctly or suggest me for correct thread
stopping function. 
BTW, I can't just leave the other thread to run, it's very high CPU
consumer. 

Thank you all.
