Can main () and its parameters have attributes?

In standard C ++, can a function main

and its parameters have attributes?

For example, is this the next legal one?

[[noreturn]] int main() { std::abort(); }

or something like

[[nodiscard, carries_dependency]]
int main(int argc [[maybe_unused]],
         char * argv [[carries_dependency, maybe_unused]] [])
{ /* ... function body omitted ... */ }

Yes, it is legal. There is no C ++ standard (in [basic.start.main] , [dcl.attr], or elsewhere) to prevent this from happening . You can even mark it main()

as [[deprecated]]

if you like.
