5.16 I want a different time-out!
Time and time again users realize that CURLOPT_TIMEOUT and
CURLOPT_CONNECTIMEOUT are not sufficiently advanced or flexible to cover all
the various use cases and scenarios applications end up with.
libcurl offers many more ways to time-out operations. A common alternative
is to use the CURLOPT_LOW_SPEED_LIMIT and CURLOPT_LOW_SPEED_TIME options to
specify the lowest possible speed to accept before to consider the transfer
timed out.
The most flexible way is by writing your own time-out logic and using
CURLOPT_PROGRESSFUNCTION (perhaps in combination with other callbacks) and
use that to figure out exactly when the right condition is met when the
transfer should get stopped.
