EncodeHuff

Performs Huffman encoding.

Syntax

IppStatus ippsEncodeHuff_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 number of elements in the destination vector after encoding.
pHuffState	Pointer to the Huffman encoding structure.

Description

The function ippsEncodeHuff is declared in the ippdc.h file. This function encodes data in the source buffer pSrc using the Huffman encoding structure pHuffState. The encoded data are placed in the destination buffer pDst. The actual number of elements in the destination buffer is written in pDstLen. The Huffman encoding structure must be initialized by calling the functions ippsEncodeHuffInitAlloc or ippsEncodeHuffInit 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.
