Include Files

ipps.h

Domain Dependencies

Headers: ippcore.h, ippvm.h

Libraries: ippcore.lib, ippvm.lib

Parameters

pSrcDst

Pointer to the source and destination vector.

len

Number of elements in the vector

Description

These functions rearrange all elements of the source vector pSrcDst in the ascending or descending order, respectively, and store the result in the destination vector pSrcDst.

Return Values

ippStsNoErr

Indicates no error.

ippStsNullPtrErr

Indicates an error when the pSrcDst is NULL.

ippStsSizeErr

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