You could also just use an SSL sockets library directly or look at
ZeroMQ. libcurl isn't suited to using HTTP without the HTTP.

I've submitted an XML stream parsing example as a pull request:

I dropped the PROPFIND stuff for clarity. It's probably best to keep
it to basics for this first example.

I wanted to note that this is far more efficient than the existing
XML/HTML parsing examples. The existing examples pull the entire
response into memory before starting to parse. This new example only
allocates buffers to fit the character data between tags.
This is pretty important for our use

that the command-line curl uses libcurl. If
something is possible with the curl CLI, it's possible with libcurl.
There are a couple of cases where the curl CLI provides additional
logic, like HTTP retries, on top of libcurl. But, it's never redundant
with what libcurl provides itself.

and our communication with S3, so the set of implementations needing
to interoperate is pretty limited. The goal is to checksum, not to
avoid attacks. MD5 is quite adequate for that. I would like to use a

Oh, actually it looks like you can make the transfer fail right from
the CURLOPT_WRITEFUNCTION, which means you could just have it return
zero. You would have to expect libcurl to consider the request failed,
