Control.Lens.Internal.CTypes

Description

In Control.Lens.Wrapped, we need to muck around with the internals of the newtypes in Foreign.C.Types. Unfortunately, the exact types used varies wildly from platform to platform, so trying to manage the imports necessary to bring these types in scope can be unwieldy.

To make things easier, we use this module as a way to import everything carte blanche that might be used internally in Foreign.C.Types. For now, this consists of all the exports from the Data.Int and Data.Word modules, as well as the Ptr type.

Synopsis

module Data.Int
data Ptr a
module Data.Word

Documentation

module Data.Int

data Ptr a #

A value of type Ptr a represents a pointer to an object, or an array of objects, which may be marshalled to or from Haskell values of type a.

The type a will often be an instance of class Storable which provides the marshalling operations. However this is not essential, and you can provide your own operations to access the pointer. For example you might write small foreign functions to get or set the fields of a C struct.
