IppStatus ippsCopyLE_1u(const Ipp8u* pSrc, int srcBitOffset, Ipp8u* pDst, int dstBitOffset, int len);

Parameters
pSrc |
Pointer to the source vector. |
pDst |
Pointer to the destination vector. |
len |
Number of elements to copy. |
srcBitOffset |
Offset, in bits, from the first byte of the source vector. |
dstBitOffset |
Offset, in bits, from the first byte of the destination vector. |
Description
This function copies the first len elements from a source vector pSrc into a destination vector pDst.
These functions copy elements of a vector that has a 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.
For the ippsCopyLE_1u function, 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.
For the ippsCopyBE_1u function, the bit order of each byte is ordinary. It means that the first element in a vector represents the last (zero) bit of the first byte in a vector, as shown in the figure below.
Return Values
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error when the pSrc or pDst pointer is NULL. |
ippStsSizeErr |
Indicates an error when:
