CRC32_BZ2

Computes the CRC32 checksum for the source data buffer.

Syntax

IppStatus ippsCRC32_BZ2_8u(const Ipp8u*
pSrc
, int
srcLen
, Ipp32u*
pCRC32
);

Parameters
pSrc
Pointer to the source data buffer.
srcLen
Number of elements in the source data buffer.
pCRC32
Pointer to the accumulated checksum value.
Description
This function computes the checksum for
srcLen
elements of the source data buffer
pSrc
and stores it in the
pCRC32
. The checksum is computed using the CRC32 direct algorithm that is specific for the bzip2 coding.
You can use this function to compute the accumulated value of the checksum for multiple buffers by specifying as an input parameter the checksum value obtained in the preceding function call.
Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error if the
pSrc
pointer is
NULL
.
ippStsSizeErr
Indicates an error if the length of the source vector is less than or equal to 0.

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.
