Parameters
pDst
Pointer to the vector to be initialized to zero.
len
Number of elements to initialize.
Description
This function initializes the first
len
elements of the vector
pDst
to zero. If
pDst
is a complex vector, both real and imaginary parts are zeroed.
Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error when the
pDst
pointer is
NULL
.
ippStsSizeErr
Indicates an error when
len
is less than or equal to zero.

Example

The code example below shows how to use the
ippsZero
function.
IppStatus zero(void) { char src[] = “zero”; return ippsZero_8u(src, strlen(src)); }

Product and Performance Information

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.
