#include <revolution/cx.h>u32 CXCompressHuffman( const u8 *srcp, u32 size, u8 *dstp, u8 huffBitSize, u8 *work );
| srcp | The source address where the data to compress is stored. |
| size | The data size of the source to compress. |
| dstp | Needs a pointer to the compression destination buffer and a region greater than the source data size. Needs a 4-byte alignment. |
| huffBitSize | The bit size (4 or 8) to Huffman encode. |
| work | The work buffer used in Huffman compression. It requires the size of CX_HUFFMAN_COMPRESS_WORK_SIZE. Needs a 4-byte alignment. |
Returns the size of the compressed data. If the data after compression is larger than the source file, no compression will be performed and a zero will be returned.
This function performs Huffman compression and writes to a designated memory region. A region of the same size as the source data must be prepared in the compression destination buffer.
