CRC32_BZ2

Computes the CRC32 checksum for the source data buffer.

Syntax

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

Include Files

ippdc.h

Domain Dependencies

Headers: ippcore.h, ippvm.h, ipps.h

Libraries: ippcore.lib, ippvm.lib, ipps.lib

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.
