Rule 21.16 is about the types of arguments allowed for memcpy.
Seeing the subject - is it memcmp(), memcpy(), or both? (Writing from
home, where I don't have the Misra spec to hand, and hence can't check
what coverage the rule has.)
Jan
In this case the rule covers just memcmp(): "The pointer arguments to
the Standard Library function memcmp shall point to either a pointer
type, an essentially signed type, an essentially unsigned type, an
essentially Boolean type or an essentially enum type"
