EncodeZfpInit, EncodeZfpInitLong

Initializes the ZFP compression structure with default values.

Syntax

IppStatus ippsEncodeZfpInit_32f(Ipp8u* pDst, int dstLen, IppEncodeZfpState_32f* pState);

IppStatus ippsEncodeZfpInitLong_32f(Ipp8u* pDst, Ipp64u dstLen, IppEncodeZfpState_32f* pState);

Parameters

pDst	Pointer to the destination buffer for compressed data.
dstLen	Length of the destination buffer.
pState	Pointer to the ZFP compression structure.

Description

This function initializes the ZFP compression structure. Its size must be calculated by calling the function EncodeZfpGetStateSize beforehand. Use the EncodeZfpInitLong function 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 dstLen is less than or equal to zero (applies only to the EncodeZfpInit function.
