IppStatus ippsSortIndexAscend_16s_I(Ipp16s* pSrcDst, int* pDstIdx, int len);

IppStatus ippsSortIndexAscend_32s_I(Ipp32s* pSrcDst, int* pDstIdx, int len);

IppStatus ippsSortIndexAscend_32f_I(Ipp32f* pSrcDst, int* pDstIdx, int len);

IppStatus ippsSortIndexAscend_64f_I(Ipp64f* pSrcDst, int* pDstIdx, int len);

IppStatus ippsSortIndexDescend_8u_I(Ipp8u* pSrcDst, int* pDstIdx, int len);

IppStatus ippsSortIndexDescend_16u_I(Ipp16u* pSrcDst, int* pDstIdx, int len);

IppStatus ippsSortIndexDescend_16s_I(Ipp16s* pSrcDst, int* pDstIdx, int len);

IppStatus ippsSortIndexDescend_32s_I(Ipp32s* pSrcDst, int* pDstIdx, int len);

IppStatus ippsSortIndexDescend_32f_I(Ipp32f* pSrcDst, int* pDstIdx, int len);

IppStatus ippsSortIndexDescend_64f_I(Ipp64f* pSrcDst, int* pDstIdx, int len);

Parameters

pSrcDst	Pointer to the source and destination vector.
pDstIdx	Pointer to the destination vector containing indexes.
len	Number of elements in the vector

Description

The functions ippsSortIndexAscend and ippsSortIndexDescend are declared in the ipps.h file. These functions rearrange all elements of the source vector pSrcDst in the ascending or descending order, respectively, and store the elements in the destination vector pSrcDst, and their indexes in the desalination vector pDstIdx. If some elements are identical, their indexes are not ordered.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when one of the specified pointers is NULL.
ippStsSizeErr	Indicates an error when len is less than or equal to 0.
