How to stop(or cancel) a thread? Suppose I have a main thread and a 
worker thread, the worker thread does something looply,and when the 
main thread get a message indicating the process should exit, I want 
stop the worker thread,how to do that?I have read other thread 
library,their thread class supply a method called stop or cancel 
which stops the thread. Their Implementation is:the thread class has 
a data member indicating whether the thread should stop,and the 
thread function looply check the data member whether the thread 
should stop.Generally the data member's type is a bool or Event.
Is it the best way to stop the thread? How the boost to deal with 
this?
Thanks in advance.
