If curl_easy_getinfo() returns an error, you can rarely fix that by trying the
request again. The problem is probably more fundamental than so.

The key is that this function returns a CURLcode, as do many libcurl
functions. So yes, the list on that web page also includes what
curl_easy_getinfo() can return. Obviously curl_easy_getinfo() will only ever
return a subset of the available return codes.

If you get CURLE_OK back, libcurl returned information without a problem. The
information may still be that there was no response code available. As
documented on the options man page:
https://curl.haxx.se/libcurl/c/CURLINFO_RESPONSE_CODE.html
