Pike v8.1 release 6

Class System.Memory

Description

A popular demand is a class representing a raw piece of memory or a mmap'ed file. This is usually not the most effective way of solving a problem, but it might help in rare situations.

Using mmap can lead to segmentation faults in some cases. Beware, and read about mmap before you try anything. Don't blame Pike if you shoot your foot off.
