But: since Martin added the message ports to the UHD blocks, things have gotten easier; you can just add an output message port to your block and connect it to the message port of the UHD sink, and send commands there without needing to care about objects, pointers, race conditions... also, if you want to do things like defining starts and ends of burst, you might do so using the good ol' stream tags. So many possibilities!
