LShiftC

Shifts bits in vector elements to the left.

Syntax

IppStatus ippsLShiftC_8u(const Ipp8u* pSrc, int val, Ipp8u* pDst, int len);

IppStatus ippsLShiftC_16s(const Ipp16s* pSrc, int val, Ipp16s* pDst, int len);

IppStatus ippsLShiftC_16u(const Ipp16u* pSrc, int val, Ipp16u* pDst, int len);

IppStatus ippsLShiftC_32s(const Ipp32s* pSrc, int val, Ipp32s* pDst, int len);

IppStatus ippsLShiftC_8u_I(int val, Ipp8u* pSrcDst, int len);

IppStatus ippsLShiftC_16u_I(int val, Ipp16u* pSrcDst, int len);

IppStatus ippsLShiftC_16s_I(int val, Ipp16s* pSrcDst, int len);

IppStatus ippsLShiftC_32s_I(int val, Ipp32s* pSrcDst, int len);

Parameters

val

Number of bits by which the function shifts each element of the vector pSrc or pSrcDst.

pSrc

Pointer to the source vector.

pDst

Pointer to the destination vector.

pSrcDst

Pointer to the source and destination vector for the in-place operation.

len

Number of elements in the vector.

Description

This function shifts each element of the vector pSrc by val bits to the left, and stores the result in pDst.

The in-place flavors of ippsLShiftC shift each element of the vector pSrcDst by val bits to the left and store the result in pSrcDst.

Return Values

ippStsNoErr

Indicates no error.

ippStsNullPtrErr

Indicates an error when the pSrc, pDst, or pSrcDst pointer is NULL .

ippStsSizeErr

Indicates an error when len is less than or equal to 0.
