#includeIn this example, we create a new threading policy object using the ORB_var create_policy method with the PRIORITY_POLICY_TYPE value. We then add this policy to a policy list and register it with a new ORB_var object using the register_policy_set method. This allows us to use the newly created ORB_var object for multi-threaded applications. The CORBA library is typically provided as a package or library, such as in the case of the TAO (The ACE ORB) library for C++.int main() { CORBA::ORB_var orb = CORBA::ORB_init(argc, argv); CORBA::PolicyList policies; // create a threading policy that allows multiple threads CORBA::Policy_var threading = orb->create_policy(CORBA::PRIORITY_POLICY_TYPE, CORBA::ORB::_nil()); policies.length(1); policies[0] = threading; // create an object request broker with the policies CORBA::ORB_var orb_with_policies = orb->duplicate(); orb_with_policies->register_policy_set(policies); // use the orb_with_policies object for multi-threaded application // ... return 0; }
