A functionality definition is actually a function declaration that also specifies the perform’s implementation, the functionality overall body.

Alternatively, implementation data files are rarely shared with C and so really should ordinarily be distinguished from .c information,

Flag a parameter of a sensible pointer form (a type that overloads operator-> or operator*) which is copyable/movable but by no means copied/moved from inside the functionality human body, and that is never modified, and that's not handed along to a different function that can do this. Meaning the ownership semantics aren't used.

Enforcement would call for some awareness about what inside a header is meant being “exported” to consumers and what's there to empower implementation.

which make the use of by far the most mistake-vulnerable characteristics of C++ redundant, making sure that they can be banned (in our set of rules).
