Hi. Thanks for reply. I've tested print with '\n' and it works in chrome as expected (emscripten 1.25). But it does not work in safari (I can't see print before input dialog shown) 31 Окт 2014 г. 22:37 пользователь "Alecazam" <a...@figma.com> написал:
Hey Anton, You should know that fflush(stdout) was implemented in a patch to the code recently. It was a no-op before. You might just need to sync to that. /n should definitely not lead to an automatic fflush. That's not the way printf functions, which is supposed to buffer output. I never use cout. cout is the worst api for atomicity and brevity of formatting.
