HuffLenCodeTablePack

Packs the table containing lengths of Huffman codes.

Syntax

IppStatus ippsHuffLenCodeTablePack_8u(const int codeLenTable[256], Ipp8u* pDst, int* pDstLen);

Parameters

codeLenTable	Table containing lengths of Huffman codes.
pDst	Pointer to the destination buffer.
pDstLen	Pointer to the number of elements in the destination buffer; after operation to the actual number of elements in the destination buffer.

Description

The function ippsHuffLenCodeTablePack is declared in the ippdc.h file. This function compresses the table codeLenTable containing lengths of Huffman codes and that is required for decoding. The table may be retrieved by calling the function ippsHuffGetLenCodeTable. To restore the table from the compressed form, call the function ippsHuffLenCodeTableUnpack.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error if one of the specified pointers is NULL.
ippStsSizeErr	Indicates an error if pDstLen is less than or equal to 0; or if pDstLen is less than actual size of the output.
