PackHuffContext

Performs the bzip2-specific encoding of Huffman context.

Syntax

IppStatus ippsPackHuffContext_BZ2_16u8u(Ipp32u* pCode, int* pCodeLenBits, Ipp8u* pDst, int* pDstLen, IppEncodeHuffState_BZ2* pEncodeHuffState);

Parameters

pCode	Pointer to the bit buffer.
pCodeLenBits	Number of valid bits in the bit buffer.
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 ippsPackHuffContext_BZ2 is declared in the ippdc.h file. This function performs the bzip2-specific encoding of the Huffman context. 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 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.
