fd-chunk-store

implement a chunk store over a single file descriptor

example

var Store = require('fd-chunk-store')
 
var store = Store(5, './wow')
store.put(0, new Buffer('hello'), function (err) {
  store.get(0, function (err, buf) {
    console.log(buf)
  })
})

output:

<Buffer 68 65 6c 6c 6f>

api

var Store = require('fd-chunk-store')

var store = Store(size, path)

var store = Store(size, opts)

Create a store with chunks size bytes long at opts.path.

store.on('open', function () {})

When the underlying file descriptor is opened, 'open' fires.

store.get(i, opts={}, cb)

Get the chunk at index i as cb(err, buf).

store.put(i, buf, opts={}, cb)

Put the chunk in buf at chunk offset i.

store.destroy(cb)

Close the underlying file descriptor and destroy the underlying resource, removing the file.

store.close(cb)

Close the underlying file descriptor.
