[go] cgoは使いたくないけど、C.GoBytes() は使いたいみたいなー [追記あり] ref: http://qiita.com/zetamatta/items/eb233ad17c15b31b2359

file0.go

var msvcrt = syscall.NewLazyDLL("msvcrt")
var memcpy = msvcrt.NewProc("memcpy")

func CGoBytes(p, length uintptr) []byte {
    buffer := make([]byte, length)
    memcpy.Call(uintptr(unsafe.Pointer(&buffer[0])), p, length)
    return buffer
}

func CGoStringN(p, length uintptr) string {
    return string(CGoBytes(p, length))
}
