Hi Marcus
Thanks for the quick answer. I didn’t know about nitems_written(0)
but I did wonder why the system didn’t already know. It’s been
a while since I used GDB but I will have a go.
I don’t quite understand - when you say "do make sure
your string isn’t going to be longer than your noutput_items" I
don’t know what that means because that’s something coming
from the scheduler isn’t it? If so how can I know beforehand what
that number is? I know a few hundred bytes that will be triggered
by the one last input bit for the packet.
I am afraid any of the tagged streams or messages are a bit
of a mystery to me.
Mike
