C 7 memcpy - copy byte string

#include <string.h>

void *
memcpy(void *dst, const void *src, size_t len);

Memcpy copies len bytes from string src to string dst and returns the original value of dst . bcopy(3), memccpy(3), memmove(3), strcpy(3) Memcpy conforms to ANSI X3.159-1989 (``ANSI C''). In this implementation memcpy is implemented using bcopy (3), and therefore the strings may overlap. On other systems, copying overlapping strings may produce surprises. A simpler solution is to not use memcpy .
