EncodeHuffInitAlloc

Allocated memory an initializes the elements of the bzip2-specific internal state for Huffman encoding.

Syntax

IppStatus ippsEncodeHuffInitAlloc_BZ2_16u8u(int wndSize, int sizeDictionary, const int freqTable[258], const Ipp16u* pSrc, int srcLen, IppEncodeHuffState_BZ2** ppEncodeHuffState);

Parameters

wndSize	Size in bytes of the block to be processed.
sizeDictionary	Size of the dictionary.
freqTable	Table of frequencies of symbols.
pSrc	Pointer to the source vector.
srcLen	Length of the source vector.
ppEncodeHuffState	Double pointer to the state structure for bzip2 specific Huffman coding.

Description

The function ippsEncodeHuffInit_BZ2 is declared in the ippdc.h file. This function allocates memory and initializes the elements of the bzip2-specific internal state pEncodeHuffState for Huffman encoding. This structure is used by the function ippsEncodeHuff_BZ2.

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 buffer is less than or equal to 0.
