A question for Rule8.13

[misra-c]

Rule 8.13 covers all pointers, which includes the "pointer parameter to function" that was covered by rule 16.7 in MISRA-C:2004.

It was felt that programmers should be encouraged to use const where possible and not just on function parameters.

Code:

int32_t fn ( int32_t *ptr )  /* not compliant */
{
   int32_t *myptr = ptr;     /* not compliant */
   return *myptr;
}

int32_t fn2 ( const int32_t *ptr2 )  /* compliant */
{
   const int32_t *myptr2 = ptr2;     /* compliant */
   return *myptr2;
}
