nn::cx::CompressHuffman Function

#include <nn/cx.h>

u32 CompressHuffman(
     const u8 * srcp,
     u32 size,
     u8 * dstp,
     u8 huffBitSize,
     void * work
);

	Name	Description
in	srcp	Pointer to compression source data.
in	size	Compression source data size.
out	dstp	Pointer to compression target data (requires a buffer larger than the compression source data).
in	huffBitSize	Number of encoded bits.
in	work	Temporary buffer to use for compression (requires a region of nn::cx::HUFFMAN_COMPRESS_WORK_SIZE bytes).

Returns the size of the compressed data. If the compressed data is larger than the original data, compression is terminated and 0 is returned.

Carries out Huffman compression.

Argument values must adhere to the following restrictions:

• huffBitSize must be 4 or 8.
• The address for work must be aligned to 4 bytes.
• The value of size must be larger than 4.
