c++ - Interrupt cin while loop without the user entering input -

-

In the main , I give the user the ability to enter commands to stop the application: 

  while (run_processes and amp; cin & gt; & gt; Kmmand_lain_input) {

I set to stop anywhere app Wish / run_processes = false; .

However, when i would run_processes set to false , then stops without entering the above loop user input.

How can I properly interrupt the loop without entering user input?

portable way std :: cin is not possible to disrupt.

You can still solve a non-portable solution, e.g. Manually poll () standard input on a UNIX system and check run_processes while voting.
