From looking at the source code related to the CURLMOPT_PUSHFUNCTION
callback, looks like there is no way to signal libcurl to cancel the request
with an error from inside it, is that the case?
Yes, the push callback only controls how to deal with that particular push. It
never struck me that an application might want to kill off the entire
connection there.
I wouldn't mind adding a new return code that would make it do that, but until
then I propose you work around that by returning an error from another
callback (like the progress one perhaps) in the mean time.
