Greetings, Is there a smart way to delete a GNU Radio block in C++? Until now I have been using the shared_ptr().reset() method but it seems to me that it will only call the destructor if the parent top_block has not been run.
This gives me problems when I try to delete and recreate a hardware input block (e.g. gr-audio input) where the new device can be the same as the old one, in which case it will report "device busy". The specific code in question is here: https://github.com/csete/gqrx/blob/afd02e241f0569e485ecbb1c312599ba60c5431c/applications/gqrx/receiver.cpp#L112 It makes no difference if I stop() the top block before attempting the reset(). Perhaps these hardware input blocks are coded incorrectly and should close the device in their stop() method? Or is there something else we can do?
