// sometimes you get a variable length array that is terminated by a NULL byte.
var buf = new Buffer(int.size * 3)
int.set(buf, int.size * 0, 5)
int.set(buf, int.size * 1, 8)
int.set(buf, int.size * 2, 0) // <- terminate with 0s

// you can create an array instance with the length automatically determined
var array = IntArray.untilZero(buf)
console.log(array.length)
// 2
console.log(array)
// [ 5, 8 ]
