C attribute: fallthrough (since C23) -

Indicates that the fall through from the previous case label is intentional and should not be diagnosed by a compiler that warns on fallthrough.

-

Syntax

- -
[[ fallthrough ]]
[[ __fallthrough__ ]]

Explanation

May only be used in an attribute declaration to create a fallthrough declaration ([[fallthrough]];).

-

A fallthrough declaration may only be used in a switch statement, where the next block item (statement, declaration, or label) to be encounted is a statement with a case or default label for that switch statement.

-

Indicates that the fall through from the previous case label is intentional and should not be diagnosed by a compiler that warns on fallthrough.

-

Example

#include <stdbool.h>
- 
-void g(void) {}
-void h(void) {}
-void i(void) {}
- 
-void f(int n) {
-  switch (n) {
-    case 1:
-    case 2:
-      g();
-     [[fallthrough]];
-    case 3: // no warning on fallthrough
-      h();
-    case 4: // compiler may warn on fallthrough
-      if(n < 3) {
-          i();
-          [[fallthrough]]; // OK
-      }
-      else {
-          return;
-      }
-    case 5:
-      while (false) {
-        [[fallthrough]]; // ill-formed: no subsequent case or default label
-      }
-    case 6:
-      [[fallthrough]]; // ill-formed: no subsequent case or default label
-  }
-}
- 
-int main(void) {}
