Bonita Montero <Bonita.Montero@gmail.com>: Oct 12 09:36AM +0200 Is there any guarantee the standard makes that random_device shoudn't start at the same internal state for all new threads, i.e. the output of the following code is likey to be different on both lines? #include <iostream> #include <mutex> #include <random> #include <thread> using namespace std; int main() { auto thr = []() { static mutex mtx; random_device rd; mtx.lock(); cout << rd() << endl; mtx.unlock(); }; thread t1( thr ); thread t2( thr ); t1.join(); t2.join(); } |

No. -- press any key to continue or any other to quit...

I guess that highly depends on compiler and OS... why don't you try out? -- press any key to continue or any other to quit...

You are stupud because you don't understand that when a standard library behaves like I wish it may not be portable because this behaviour might not be specified. So it wouldn't be clever to rely on this only because an implementation has this behaviour. Boy, you're always telling stupid stuff. Stop writing about such things; it's always embarrassing for you. |
