Why is volatile not considered useful in multithreaded C or C++ programming? http://stackoverflow.com/questions/2484980/why-is-volatile-not-considered-useful-in-multithreaded-c-or-c-programming variables modified by another thread all constitute such situations. So if you have a global int foo and foo is read by one thread.. machine instruction the reading thread sees this situation in the same way it sees a variable tweaked by a signal handler.. thus foo should be declared volatile or for multithreaded situations accessed with memory fenced load which is probably a better..
