Hello Patrick Diehl: Thank you very much for taking time reading my proposal. The opinion you give is really helpful. I read the irc history and make some change on my proposal draft. If you have time, can you go over it again and give me more advises. The shared link is not changed.
Furthermore, when I am writing my proposal today, I come up with a question: What will happen if a task runs on an hpx thread and it call some non-hpx thread. Today, I try to write a small program using VideoCapture in the main hpx thread. I initialize the hpx run time, in the hpx_main function, I open my webcam and use highgui to display the captured image. I look at the windows resource manager, the program has 21 threads. It seems VideoCapture generates so many threads. I believe they can not be hpx-thread, right? But it seems nothing bad happens, the small example just works as I think.
