Parameters
pCode
Pointer to the bit buffer.
pCodeLenBits
Number of valid bits in the bit buffer.
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 encoding of the
Huffman context
. 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 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.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
