Hi All I am playing with boost::thread and it is not clear how thread::interrupt actually works.
If I understood clearly the thread will be interrupted the next time it enters one of the predefined interruption points; since thread::join is one interruption point, after I call tr.interrupt() I am expected that the thread will throw a boost::thread_interrupted exception once I call tr.join() right? .
I believe that if your thread had started a second thread and was waiting on thread::join() for the second level thread to finish, and if you called thread::interrupt on the first thread, then you would see the exception. i.e. void levelTwo (void) { while (true) { ; } } void levelOne (void) { try { boost::thread t2 (levelTwo); t2.join(); } catch (const boost::thread_interrupted& ex ) { std::cout << "levelOne was interrupted" << std::endl; } } int main( int argc, char** argv ){ boost::thread t1( levelOne ); boost::this_thread::sleep( boost::posix_time::seconds( 3 ) ); std::cout << "calisl to INTER." << std::endl; std::cout.flush(); t1.interrupt(); } - Rush
