nn::cx Namespace

Description

Namespace for the file compression and decompression library.

Structures

nn::cx::UncompContextRL The context for decompressing run-length compressed data.
nn::cx::UncompContextLZ The context for decompressing LZ77 compressed data.
nn::cx::UncompContextHuffman The context for decompressing Huffman compressed data.
nn::cx::UncompContextLH The context for decompressing LZ-Huffman compressed data.
nn::cx::UncompContextLRC The context for decompressing LZ-Range Coder compressed data.

Enumerated Types

CompressionType Enumerated type representing compression types.

Functions
