I think ASSERT_TRUE would be nice here

[thatguysumeetkumar-code]

If I understood correctly ASSERT_TRUE(ipcServer.init(makeUniqueIpcName()) == ifappl::CheckpointIpcServer::EIpcInitResult::kOk) << "CheckpointIpcServer init failed";

[MaciejKaszynski]

Would it make sense to assert here? otherwise we are in an undefined state

[thatguysumeetkumar-code]

If I understood correctly const auto init_result = ipc_request_semaphore_.init(1U, false); assert((score::lcm::internal::osal::OsalReturnType::kSuccess == init_result) && "ControlClient semaphore initialization failed");

[MaciejKaszynski]

Actually there are baselibs asserts, think we should be using it SCORE_LANGUAGE_FUTURECPP_ASSERT_PRD_MESSAGE since this would be useful info for user. https://github.com/eclipse-score/baselibs/blob/866daca52e8d886a04628be138800d103a5c015b/score/language/futurecpp/include/score/assert.hpp
