The source needs to be validated up to min(passed size, strlen).
Basically this means implementing the function, as there is no other way
than iterate it to find the NULL terminator, and you may as well do the

No, you only need to restrict the passed size to the valid range; no
need to actually read data (unless I missed something.)
