[Cbc] Terminating cbc run

[Fei Peng]

Hi,

I recently ran into a problem about terminating cbc: I have a few 
different cbcmodel's built and running concurrently on different 
threads, and at some point I might decide to stop some of them from 
continuing to run, and kill that thread.

I understand that pthread_cancel will only cancel the execution of a 
thread when it runs into a predefined set of codes, and it's not done 
immediately after I call pthread_cancel() -- in which case each thread 
I'm cancelling will need to wait for it's cbcmodel to finish and then 
cancel. My question is: is there a way to signal cbc in the middle of 
the optimization, so that it stops immediately?  Is sayEventHappened() 
designed to do this? Please advise

Thanks!
Fei
