You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: process_windows.go
    path of file: ./repos/octant/vendor/github.com/hashicorp/go-plugin
    
    the code of the file until where you have to start completion: package plugin

import (
	"syscall"
)

const (
	// Weird name but matches the MSDN docs
	exit_STILL_ACTIVE = 259

	processDesiredAccess 
    
func _pidAlive(pid int) bool {
	h, err := syscall.OpenProcess(processDesiredAccess, false, uint32(pid))
	if err != nil {
		return false
	}

	var ec uint32
	if e := syscall.GetExitCodeProcess(h, &ec); e != nil {
		return false
	}

	return ec == exit_STILL_ACTIVE
}
