DecodeHuffInitAlloc

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

Syntax

IppStatus ippsDecodeHuffInitAlloc_BZ2_8u16u(int wndSize, int sizeDictionary, IppDecodeHuffState_BZ2** ppDecodeHuffState);

Parameters

wndSize	Size in bytes of the block to be processed.
sizeDictionary	Size of the dictionary.
pDecodeHuffState	Pointer to the state structure for bzip2 specific Huffman decoding.

Description

The function ippsDecodeHuffInitAlloc_BZ2 is declared in the ippdc.h file. This function allocates memory and initializes the elements of the bzip2-specific internal state pDecodeHuffState for Huffman decoding. This structure is used by the function ippsDecodeHuff_BZ2.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error if the pDecodeHuffState pointer is NULL.
ippStsSizeErr	Indicates an error if sizeDictionary or wndSize is less than or equal to 0.
