EncodeHuff_BZ2

Performs the bzip2-specific Huffman encoding.

Syntax

IppStatus ippsEncodeHuff_BZ2_16u8u(Ipp32u* pCode, int* pCodeLenBits, Ipp16u** ppSrc, int* pSrcLen, Ipp8u* pDst, int* pDstLen, IppEncodeHuffState_BZ2* pEncodeHuffState);

Parameters

pCode

Pointer to the bit buffer.

pCodeLenBits

Number of valid bits in the bit buffer.

ppSrc

Double pointer to the source vector.

pSrcLen

Pointer to the length of source vector.

pDst

Pointer to the destination vector.

pDstLen

Pointer to the size of destination buffer on input, pointer to the resulting length of the destination vector on output.

pEncodeHuffState

Pointer to internal state structure for bzip2 specific Huffman encoding.

Description

The function ippsEncodeHuff_BZ2 is declared in the ippdc.h file. This function performs the bzip2-specific Huffman encoding. The function uses the bzip2-specific Huffman encoding state structure pEncodeHuffState. This structure must be initialized by the functions ippsEncodeHuffInitAlloc_BZ2 or ippsEncodeHuffInit_BZ2 beforehand.

Return Values

ippStsNoErr

Indicates no error.

ippStsNullPtrErr

Indicates an error if one of the pointers is NULL.

ippStsSizeErr

Indicates an error if length of the source or destination buffer is less than or equal to 0.

ippStsDstSizeLessExpected

Indicates a warning if size of the destination buffer is insufficient to store all output elements.
