MakeIAMPolicyConnection(Options)\n\nA factory function to construct an object of type [`IAMPolicyConnection`](/cpp/docs/reference/iam/latest/classgoogle_1_1cloud_1_1iam__v1_1_1IAMPolicyConnection). \nThe returned connection object should not be used directly; instead it should be passed as an argument to the constructor of [IAMPolicyClient](/cpp/docs/reference/iam/latest/classgoogle_1_1cloud_1_1iam__v1_1_1IAMPolicyClient).\n\nThe optional `options` argument may be used to configure aspects of the returned [`IAMPolicyConnection`](/cpp/docs/reference/iam/latest/classgoogle_1_1cloud_1_1iam__v1_1_1IAMPolicyConnection). Expected options are any of the types in the following option lists:\n\n- [`google::cloud::CommonOptionList`](https://cloud.google.com/cpp/docs/reference/common/latest/namespacegoogle_1_1cloud.html)\n- [`google::cloud::GrpcOptionList`](https://cloud.google.com/cpp/docs/reference/common/latest/namespacegoogle_1_1cloud.html)\n- [`google::cloud::UnifiedCredentialsOptionList`](about:invalid#zCSafez)\n- [`google::cloud::iam_v1::IAMPolicyPolicyOptionList`](about:invalid#zCSafez)\n\n| **Note:** Unexpected options will be ignored.
