That sentence no verb. I point that out because that fact that is has no
verb is part of the reason why I'm not sure what you meant by it. The
term "string", as defined by the C standard, is by definition
null-terminated, and does not have a stored length.

Any given use might seem ambiguous to a newbie like yourself, but the
reason why it is commonplace to use "string pointer" without following
it with "value", "object", "type", or "expression" is precisely because
it's usually clear from context (at least to those with more experience
with the language) which of those is being referred to. When it would
otherwise be ambiguous, people usually (but unfortunately, not always)
do add the additional word that's needed to make it clear.
