FSExtentPacker

A type that directs the kernel to map space on disk to a specific file managed by this file system.

Declaration

class FSExtentPacker

Overview

Extents provide the kernel the logical-to-physical mapping of a given file. An extent describes a physical offset on disk, and a length and a logical offset within the file. Rather than working with extents directly, you use this type’s methods to provide or “pack” extent information, which FSKit then passes to the kernel.
