Function Comparison of C++11thread detach () and join () __jquery

After declaring a Std::thread object, you can use the detach and join functions to start the tuned thread , which is the difference between whether they block the keynote thread or not.

(1) when the join () function is used, the keynote thread blocks, waits for the thread to terminate, and then the thread reclaims the thread resource and continues to run;

(2) When using the detach () function, the keynote thread continues to run, the thread that is being tuned to run in the background, the keynote thread can no longer take control of the tuned thread. When the keynote thread ends, the Run-time library is responsible for cleaning up resources associated with the thread being tuned.
