Parameters
- pSrc
- Pointer to the source vector.
- pDst
- Pointer to the destination vector.
- len
- Number of elements to copy.
Description
This function copies the first
len
elements from a source vector
pSrc
into a destination vector
pDst
.
ippsCopy_1u
8u
data type. It means that each byte consists of eight consecutive elements of the vector (1 bit per element). You need to specify the start position of the source and destination vectors in the
srcBitOffset
and
dstBitOffset
parameters, respectively. The bit order of each byte is inverse to the element order. It means that the first element in a vector represents the last (seventh) bit of the first byte in a vector, as shown in the figure below.
Bit Layout for the Function
ippsCopy_1u
.
These functions perform only copying operations described above and are not intended to move data. Their behavior is unpredictable if source and destination buffers are overlapping. To move data, use
ippsMove
.
Return Values
- ippStsNoErr
- Indicates no error.
- ippStsNullPtrErr
- Indicates an error when thepSrcorpDstpointer isNULL.
- ippStsSizeErr
- Indicates an error whenlenis less than or equal to zero.
Example
The example below shows how to use the
ippsCopy
function.IppStatus copy(void) { char src[] = “to be copied\0”; char dst[256]; return ippsCopy_8u(src, dst, strlen(src)+1); }
