Parameters
val
Number of bits by which the function shifts each element of the vector
pSrc
or
pSrcDst
.
pSrc
Pointer to the source vector.
pDst
Pointer to the destination vector.
pSrcDst
Pointer to the source and destination vector for the in-place operation.
len
Number of elements in the vector.
Description
This function shifts each element of the vector
pSrc
by
val
bits to the left, and stores the result in
pDst
.
The in-place flavors of
ippsLShiftC
shift each element of the vector
pSrcDst
by
val
bits to the left and store the result in
pSrcDst
.
Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error when the
pSrc
,
pDst
,
or pSrcDst
pointer is
NULL
.
ippStsSizeErr
Indicates an error when
len
is less than or equal to 0.
