Data.Array.Storable (original) (raw)

Contents

• Arrays of Storable things.
• Overloaded mutable array interface
• Accessing the pointer to the array contents

Description

A storable array is an IO-mutable array which stores its contents in a contiguous memory block living in the C heap. Elements are stored according to the class Storable. You can obtain the pointer to the array contents to manipulate elements from languages like C.

It is similar to [IOUArray](Data-Array-IO.html#v:IOUArray "Data.Array.IO") but slower. Its advantage is that it's compatible with C.
