DecodeLZ4

Performs LZ4 decoding.

Syntax

IppStatus ippsDecodeLZ4_8u(const Ipp8u* pSrc, int srcLen, Ipp8u* pDst, int* pDstLen);

Include Files

ippdc.h

Domain Dependencies

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

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

Parameters

pSrc

Pointer to the source data.

srcLen

Length of the source data for decompression.

pDst

Pointer to the compressed data.

pDstLen

Pointer to the length of the uncompressed data.

Description

This function performs decoding of the source data pSrc using the LZ4 algorithm. The destination buffer must have sufficient length for the operation. The length of the uncompressed data is set to pDstLen.

Return Values

ippStsNoErr

Indicates no error.

ippStsNullPtrErr

Indicates an error if at lease one of the specified pointers is NULL.

ippStsSizeErr

Indicates an error if the srcLen value is less than, or equal to zero.

ippStsMemAllocErr

Indicates an error if the size of the allocated memory is not sufficient for decompression.
