. This function flavor copies elements of a vector that has a
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
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.
