# CFAllocatorContext

A structure that defines the context or operating environment for an allocator (CFAllocator) object. Every Core Foundation allocator object must have a context defined for it.

## Declaration

```swift
struct CFAllocatorContext
```

## Overview

Overview See the Memory Management Programming Guide for Core Foundation topic for information on creating a custom CFAllocator object and, as part of that procedure, the steps for creating a properly initialized CFAllocatorContext structure.
