Should useless type qualifiers on return types be used, for clarity?

Question

Our static analysis tool complains about a \"useless type qualifier on return type\" when we have prototypes in header files such as:

const int foo();
         


        

Answer 1

You can use a different technique to illustrate your intent without making the tools unhappy.

#define CONST_RETURN

CONST_RETURN int foo();

You don't have a problem with const char * because that's declaring a pointer to constant chars, not a constant pointer.
