Coding standards

Code examples

The following code example fails the check and will give a warning:

struct A { 
  int _Atomic x; 
  int _Atomic y;
};

void main() {
   struct A a1 = { 6, 7 }; 
   void _Atomic * pav = &a1; /* Non-compliant */ 
   void _Atomic * pax = &a1.x; /* Non-compliant */
}

The following code example passes the check and will not give a warning about this issue:

struct A { 
  int _Atomic x; 
  int _Atomic y;
};

void main() {
   struct A a = { 6, 7 }; 
   int _Atomic * px = &a.x; /* Compliant */ 
}
