AutoCorrNormGetBufferSize

Computes the size of the work buffer for the ippsAutoCorrNorm function.

Syntax

IppStatus ippsAutoCorrNormGetBufferSize (int srcLen, int dstLen, IppDataType dataType, IppEnum algType, int* pBufferSize);

Include Files

ipps.h

Parameters

srcLen	Number of elements in the source vector.
dstLen	Number of elements in the destination vector (length of auto-correlation).
dataType	Data type for auto-correlation. Possible values are ipp32f, ipp32fc, ipp64f, or ipp64fc.
algType	Bit-field mask for the algorithm type definition. Possible values are the results of composition of the IppAlgType and IppsNormOp values.
pBufferSize	Pointer to the size of the work buffer.

Description

The ippsAutoCorrNormGetBufferSize function computes the size in bytes of the external work buffer needed for the function that performs auto-correlation. The result is stored in the pBufferSize parameter.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when pBufferSize is NULL.
ippStsSizeErr	Indicates an error when srcLen or dstLen is less than, or equal to zero.
ippStsAlgTypeErr	Indicates an error when: the result of the bitwise AND operation between the algType and ippAlgMask differs from the ippAlgAuto, ippAlgDirect, or ippAlgFFT values; the result of the bitwise AND operation between the algType and ippsNormMask differs from the ippsNormNone, ippsNormA, or ippsNormB values.
ippStsDataTypeErr	Indicates an error when the dataType value differs from the ipp32f, ipp32fc, ipp64f, or ipp64fc.
