Windows has always been weak.

@lucktu @Logan007 you can tell me which function should be called when ctrl+c on windows,I will do it

I have observed the extra thread (Windows only!) not immediately reacting, i.e. it took some seconds to terminate the edge after CTRL + C, but so far, I have never went deeper into it.

I guess we need to investigate the tun_read_thread in more detail.

but it works on linux

There is no need for a chhild process / thread in Linux as TAP handling works differently.

I think you can call send_unregister_super first when ctrl+c

:+1: Will change it.

This however probably does not solve the blocking WaitForSingleObject. I went a bit into it suspecting the IO to be blocking, but realized thatwin32/wintap.c opens it with FILE_FLAG_OVERLAPPED... so, I am a bit puzzled here.

[introspection3]

I found that it may be blocked in while loop

i have pulled request,please check it ,you can make the code better

[Logan007]

Thank you, I will have a look.
