DecodeZfpInit, DecodeZfpInitLong

Initializes the ZFP decompression structure with default values.

Syntax

IppStatus ippsDecodeZfpInit_32f(const Ipp8u* pSrc, int srcLen, IppDecodeZfpState_32f* pState);

IppStatus ippsDecodeZfpInitLong_32f(const Ipp8u* pSrc, Ipp64u srcLen, IppDecodeZfpState_32f* pState);

Headers: ippcore.h, ippvm.h, ipps.h

Libraries: ippcore.lib, ippvm.lib, ipps.lib

Parameters

pSrc	Pointer to the input buffer holding the compressed data.
srcLen	Length of the compressed data buffer.
pState	Pointer to the ZFP decompression structure.

Description

This function initializes the ZFP decompression structure. Before using this function, calculate the size of the structure calling the DecodeZfpGetStateSize function.

Use ippsDecodeZfpInitLong to process large 3D floating point arrays.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error if any of the pointers is NULL.
ippStsSizeErr	Indicates an error if the parameter srcLen is less than or equal to zero (applies only to ippsDecodeZfpInit).
