DecodeLZ77GetPairs

Retrieves pair data from the LZ77 decoding state structure.

Syntax

IppStatus ippsDecodeLZ77GetPairs_8u(IppLZ77Pair** ppPairs, int* pPairsInd, int* pPairsLen, IppLZ77State_8u* pLZ77State);

Parameters

ppPairs	Double pointer to the pair buffer.
pPairsInd	Pointer to the current index in the pair buffer.
pPairsLen	Pointer to the length of the pair buffer.
pLZ77State	Pointer to the initialized LZ77 decoding state structure.

Description

The ippsDecodeLZ77GetPairs function is declared in the ippdc.h file. This function returns the following pointers: ppPairs to the pair buffer, pPairsLen to the length of the pair buffer, and pPairsInd to the current index. These pointers are retrieved from the initialized LZ77 decoding state structure pLZ77State.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error if the pLZ77State or pPairs pointer is NULL.
