FSMutableFileDataBuffer

A wrapper object for a data buffer.

Declaration

class FSMutableFileDataBuffer

Overview

This object provides a “zero-copy” buffer, for use when reading data from files. By not requiring additional buffer copying, this object reduces the extension’s memory footprint and improves performance. The FSMutableFileDataBuffer behaves similarly to a uio in the kernel.
