Parameters
pLitSrc |
Pointer to the literals/lengths source vector. |
pDistSrc |
Pointer to the distances source vector. |
srcLen |
Length of the source vectors. |
pCode |
Pointer to the bit buffer. |
pCodeLenBits |
Pointer to the number of valid bits in the bit buffer. |
pLitHuffCodes |
Pointer to the literals/lengths Huffman codes. |
pDistHuffCodes |
Pointer to the distances Huffman codes. |
pDst |
Pointer to the destination vector. |
pDstIdx |
Pointer to the index in the destination vector. |
Description
This function performs Huffman encoding of source data.
The function parameter pDstIdx returns the index of the current position in the destination vector: zlib uses the intermediate buffer for the Huffman encoding and we need to know the indexes of the first (input parameter) and the last (output parameter) symbols, which are written by the function.
Return Values
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error if one of the specified pointers is NULL. |
