Parameters
pCode
Pointer to the bit buffer.
pCodeLenBits
Number of valid bits in the bit buffer.
ppSrc
Double pointer to the source vector.
pSrcLen
Pointer to the length of source vector.
pDst
Pointer to the destination vector.
pDstLen
Pointer to the size of destination buffer on input, pointer to the resulting length of the destination vector on output.
pEncodeHuffState
Pointer to internal state structure for bzip2 specific Huffman encoding.
Description
This function performs the bzip2-specific Huffman encoding. The function uses the bzip2-specific Huffman encoding state structure
pEncodeHuffState
. This structure must be initialized by
ippsEncodeHuffInit_BZ2
beforehand.
Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error if one of the pointers is
NULL
.
ippStsSizeErr
Indicates an error if length of the source or destination buffer is less than or equal to 0.
ippStsDstSizeLessExpected
Indicates a warning if size of the destination buffer is insufficient to store all output elements.
