Paul Hollinsky c32d027b2d MessageCallback: Tolerate being created with nullptr filter ... Communication does this in waitForMessageSync if a filter is not passed in. This fixes a crash in icsneoWaitForRxMessagesWithTimeOut for the legacy API. For good measure, creation with an empty std::function will immediately throw an std::bad_function_call back at the caller, rather than letting that happen on the callback thread. I'm also making the members const here so they are provably always non-null (and not empty, for the function).		2022-02-21 22:55:49 -05:00
