How to asynchronously read input from command line using boost asio in Windows?

Question

I found this question which asks how to read input asynchronously, but will only work with POSIX stream descriptors, which won\'t work on Windows. So, I found this tutorial

Answer 1

You need to initialize your stream_handle to the console input handle. You can't use the same stream_handle for input and for output because those are two different handles.

For input:

    Example()
        : /* ... */ input_handle( io_service, GetStdHandle(STD_INPUT_HANDLE) )

For output you would use CONSOLE_OUTPUT_HANDLE. But that is probably overkill, you're unlikely to be pushing that much data into stdout on windows that you'd need to use an async write.
