The problem I am having is with dropped internet connections when this
function is already running. In such situations I would like U = 0 so
that the main loop ends and the function returns back to its origin.
This isn't happening. Most of the time after the internet connection
is dropped and then re-established, the function is stuck in the main
while loop with U != 0.
I suppose that's simply because libcurl didn't actually trigger an error
for those cases so all that happened was that when the internet
connection "dropped" your transfers stalled, waiting for the
connectivity to come back. TCP is after all designed to work exactly
like that.
If you want to detect that better, you should consider setting
CURLOPT_TCP_KEEPALIVE and/or to use some timeouts like
CURLOPT_LOW_SPEED_LIMIT / CURLOPT_LOW_SPEED_TIME.
