What did you do?

review code in https://github.com/golang/go/blob/master/src/os/exec_posix.go#L13
https://github.com/golang/go/blob/master/src/os/exec_windows.go#L71

What did you expect to see?

os.Interrupt can not send in windows system. it will return a error message with "not supported by windows"

What did you see instead?

// The only signal values guaranteed to be present on all systems
// are Interrupt (send the process an interrupt) and Kill (force
// the process to exit).

os.Process.Signal says:

// Signal sends a signal to the Process.
// Sending Interrupt on Windows is not implemented.

os.Process.Signal says about this,but it was not on the os.Interrupt which misleading me to think that os.Process.Signal(os.Interrupt) is working on windows.

There's a TODO: // TODO(rsc): Handle Interrupt too?

Does Windows support SIGINT?

Does Windows support SIGINT?

I searched this issue list for SIGINT and I find #7479 and #17608 that probably relate to this.

I don't think the document is misleading.

// The only signal values guaranteed to be present on all systems
// are Interrupt ......

So Windows does support SIGINT.

// Sending Interrupt on Windows is not implemented.

Go doesn't support sending SIGINT on Windows.
It hasn't been implemented yet, and it may be supported in the future.
