use of require_auth2

Question

I'm interested in checking whether a specific permissions has been passed to a method invocation (as opposed to active) and have read one can use the require_auth2 method but when I try it I get the following error:

error: use of undeclared identifier 'require_auth2'; did you mean 'eosio::internal_use_do_not_use::require_auth2'?

so clearly this is internal and not meant to be used. how do I accomplish my goal?

Answer 1

C++ API is wrapped differently.

inline void require_auth( const permission_level& level ) {
  internal_use_do_not_use::require_auth2( level.actor.value, level.permission.value );
}

// how to use
require_auth(permission_level("eosio"_n, "vote"_n));
