The attribute ``++noreturn++`` indicates that a function does not return. 
Using this attribute allows the compiler to do some assumptions that can lead to optimizations. However, if a function with this attribute ever returns, the behavior becomes undefined.


== Noncompliant Code Example

----
[[noreturn]] void f () {
  while (1) {
    // ...
    if (/* something*/) {
      return; // Noncompliant, this function should not return
    }
  }
}
----


== Compliant Solution

----
[[noreturn]] void f() {  // Compliant
  while (true) {
    // ...
  }
}
----
Or

----
void f() {  
  while (true) {
    // ... 
    if (/* something*/) { 
      return; // Compliant 
    }
  }
}
