Parameters
sizeDictionary
Size of the dictionary.
freqTable
Table of frequencies of symbols.
pSrc
Pointer to the source vector.
srcLen
Length of the source vector.
pEncodeHuffState
Pointer to internal state structure for bzip2 specific Huffman coding.
Description
This function initializes the elements of the bzip2-specific internal state for Huffman encoding. This structure is used by the function
ippsEncodeHuff_BZ2
. The size of this buffer must be computed previously by calling the function
ippsEncodeHuffGetSize_BZ2
.
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 buffer is less than or equal to 0.
