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: zsyscall_windows.go
    path of file: ./repos/go-starter-kit/vendor/golang.org/x/sys/windows
    
    the code of the file until where you have to start completion: // MACHINE GENERATED BY 'go generate' COMMAND; DO NOT EDIT

package windows

import (
	"syscall"
	"unsafe"
)

var _ unsafe.Pointer

// Do the interface allocations only once for common
// Errno values.
const (
	errnoERROR_IO_PENDING = 997
)

var (
	errERROR_IO_PENDING error = syscall.Errno(errnoERROR_IO_PENDING)
)

// errnoErr returns common boxed Errno values, to prevent
// allocations at runtime.
func errnoErr(e syscall.Errno) error {
	switch e {
	case 0:
		return nil
	cas
    
func CreateFile(name *uint16, access uint32, mode uint32, sa *SecurityAttributes, createmode uint32, attrs uint32, templatefile int32) (handle Handle, err error) {
	r0, _, e1 := syscall.Syscall9(procCreateFileW.Addr(), 7, uintptr(unsafe.Pointer(name)), uintptr(access), uintptr(mode), uintptr(unsafe.Pointer(sa)), uintptr(createmode), uintptr(attrs), uintptr(templatefile), 0, 0)
	handle = Handle(r0)
	if handle == InvalidHandle {
		if e1 != 0 {
			err = errnoErr(e1)
		} else {
			err = syscall.EINVAL
