DecodeHuff

Performs Huffman decoding.

Syntax

IppStatus ippsDecodeHuff_8u(const Ipp8u* pSrc, int srcLen, Ipp8u* pDst, int* pDstLen, IppHuffState_8u* pHuffState);

Parameters

pSrc	Pointer to the source buffer.
srcLen	Number of elements in the source buffer.
pDst	Pointer to the destination buffer.
pDstLen	Pointer to the expected number of elements in the destination buffer; after decoding to the actual number of elements in the destination buffer.
pHuffState	Pointer to the Huffman coding structure.

Description

The function ippsDecodeHuff is declared in the ippdc.h file. This function decodes the data in the source buffer pSrc containing srcLen code words. The pDstLen decoded elements are stored in the destination vector pDst. The function uses the Huffman decoding structure pHuffState that must be initialized by calling the functions ippsDecodeHuffInitAlloc or ippsDecodeHuffInit beforehand.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error if one of the specified pointers is NULL.
ippStsSizeErr	Indicates an error if srcLen is less than or equal to 0.
