Create C typed "array" instances on top of Buffers
This module offers an "array" implementation on top of Node.js Buffers using the ref "type" interface.
$ npm install ref-array
var ref =var ArrayType =// typedefvar int = reftypesint// define the "int" typevar IntArray =// now we can create array instances; the constructor takes the same arguments// the native JS Array classvar a = 5 // by lengthalength // 5a0 = 0a1 = 1a2 = -1a3 = 2a4 = -2var b = 1 2 3 4 5 // with an existing Arrayblength // 5b0 // 1b1 // 2b2 // 3b3 // 4b4 // 5
// sometimes you get a variable length array that is terminated by a NULL byte.var buf = intsize * 3intintint // <- terminate with 0s// you can create an array instance with the length automatically determinedvar array = IntArrayconsole// 2console// [ 5, 8 ]
var ffi =// the "int" type may be used as a "type" in FFI'd functions or callbacksvar func = ffivar arg = 3arg0 = 1234arg1 = -9999arg2 = 1var rtn =
