EncodeLZ77StoredBlock

Stores the data block without compression.

Syntax

IppStatus ippsEncodeLZ77StoredBlock_8u(Ipp8u** ppSrc, int* pSrcLen, Ipp8u** ppDst, int* pDstLen, IppLZ77Flush flush, IppLZ77State_8u* pLZ77State);

Parameters

ppSrc	Double pointer to the source buffer.
pSrcLen	Pointer to the length of the source buffer.
ppDst	Double pointer to the destination buffer.
pDstLen	Pointer to the length of the destination buffer.
flush	Specifies the encoding mode for data blocks (see flush Parameter).
pLZ77State	Pointer to the LZ77 encoding state structure.

Description

The ippsEncodeLZ77StoredBlock function is declared in the ippdc.h file. This function copies source data ppSrc data to the destination buffer ppDst without Huffman encoding.

The function ippsEncodeLZ77StoredBlock writes the marker of the end of the block to the output stream and aligns the output data in accordance with the specified parameter flush.

The function uses the LZ77 encoding state structure pLZ77State that must be previously initialized by the function ippsEncodeLZ77InitAlloc or ippsEncodeLZ77Init.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error if one of the specified pointers is NULL.
ippStsSizeErr	Indicates an error if DstLen is less than or equal to 0.
ippStsDstSizeLessExpected	Indicates a warning that the size of the destination buffer is insufficient for completing the operation.
