    The memccpy() function shall copy bytes from memory area s2 into s1,
    stopping after the first occurrence of byte c (converted to an
    unsigned char) is copied, or after n bytes are copied, whichever comes
    first.

I'd conclude that memccpy must not touch the memory after the character.
