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

The () function copies len bytes from string src to string dst.

The memcpy() function returns the original value of dst.

bcopy(3), memccpy(3), memmove(3), strcpy(3)

The memcpy() function conforms to ANSI X3.159-1989 (“ANSI C89”).

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().
