pSrc |
Pointer to the source data. |
srcLen |
Length of the source data for compression. |
srcIdx |
Index of the starting byte in the source vector. |
pSrcLen |
Pointer to the length of the source data for compression. |
pDst |
Pointer to the compressed data. |
pDstLen |
Pointer to the length of the compressed data. |
pHashTable |
Pointer to the LZ4 hash table. |
pDict |
Pointer to the dictionary. |
dictLen |
Length of the dictionary. |
These functions perform encoding of the source data pSrc using the LZ4 algorithm. The destination buffer must have sufficient length for the operation. The length of the compressed data is set to pDstLen.
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error if at least one of the specified pointers is NULL. |
ippStsSizeErr |
Indicates an error if the srcLen value is less than, or equal to zero. |
ippStsBadArgErr |
Indicates an error if the index of the starting byte is less than zero. |
ippStsDstSizeLessExpected |
Indicates an error if the length of the destination buffer is not sufficient. |
