Package Exports

ref-struct

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (ref-struct) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

ref-struct

Create "struct" instances using Buffers

This module offers a "struct" implementation on top of Node.js Buffers using the ref "type" interface.

Installation

Install with npm:

$ npm install ref-struct

Examples

Say you wanted to emulate the timeval struct from the stdlib:

struct timeval {
  time_t       tv_sec;   /* seconds since Jan. 1, 1970 */
  suseconds_t  tv_usec;  /* and microseconds */
};

var ref = require('ref')
var StructType = require('ref-struct')

// define the time types
var time_t = ref.types.long
var suseconds_t = ref.types.long

// define the "timeval" struct type
var timeval = StructType({
  tv_sec: time_t,
  tv_usec: suseconds_t
})

// now we can create instances of it
var tv = new timeval


// this gets very powerful when combined with `node-ffi` to invoke C functions
gettimeofday(tv.ref(), null);
