Move

Moves the contents of one vector to another vector.

Syntax

IppStatus ippsMove_16s(const Ipp16s* pSrc, Ipp16s* pDst, int len);

IppStatus ippsMove_32s(const Ipp32s* pSrc, Ipp32s* pDst, int len);

IppStatus ippsMove_32f(const Ipp32f* pSrc, Ipp32f* pDst, int len);

IppStatus ippsMove_64f(const Ipp64f* pSrc, Ipp64f* pDst, int len);

Parameters

pSrc

Pointer to the source vector used to initialize pDst.

pDst

Pointer to the destination vector to be initialized.

len

Number of elements to move.

Description

This function moves the first len elements from a source vector pSrc into the destination vector pDst. If some parts of the source and destination vectors are overlapping, then the function ensures that the original source bytes in the overlapping parts are moved (it means that they are copied before being overwritten) to the appropriate parts of the destination vector.

Return Values

ippStsNoErr

Indicates no error.

ippStsNullPtrErr

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

ippStsSizeErr

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

Example

Ipp8u pSrc[10] = { "123456789" }; 
Ipp8u pDst[6]; 
int len = 6; 
IppStatus status;

status = ippsMove_8u ( pSrc, pDst, len ); 
if(ippStsNoErr != status)
  printf("Intel(R) IPP Error: %s",ippGetStatusString(status));

Result:

pSrc = 123456789 
pDst = 123456
