Rule 3-4-1 and classes

Postby drstaiger » Wed Dec 21, 2016 10:50 am

The rule's title includes "types", but the body of the rule does not specify further whether this is meant for typedefs only, or for complex classes as well.
For example, a class only used in a single function: should it be moved into the function? That would work against the typical ideas of short functions and separation of responsibilities. Could you please clarify MISRA's intention here?

As currently stated you are correct, a class only used in a single function should be declared in that function.

However, you are also right that this may be undesirable. This will be reviewed for a future version
