iwsVector_InitExternalConst

Syntax

IW_DECL(IppStatus) iwsVector_InitExternalConst(
    IwsVector              *pVector,        
    IwSize                  size,           
    IppDataType             dataType,       
    const IwsBorderSize    *pInMemBorder,   
    const void             *pBuffer         
);
Parameters
pVector
Pointer to the
IwsVector
 structure.
size
Vector length, in elements, without the border.
dataType
Data type of vector elements.
pBuffer
Pointer to the external image buffer.
pInMemBorder
Size of the vector border; set to
NULL
 if there is no border.
pBuffer
Pointer to the external vector buffer.
Description
This function initializes the vector structure with the external read-only buffer.
Return Values
ippStsNullPtrErr
At least one of the pointers is
NULL

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
