Ok. I didnt code in C for a loooooong time, I hope my memories are not too
bad.

Thereafter a proposition :
Instead of a boolean (which btw is not a type used for CURLINFO), I finally
used 3 cases ("FALSE", "TRUE" and
It_was_true_but_you_asked_to_follow_the_location_and_this_location_needed_a_
new_connection).

curl_reused_info reused_conn;
res = curl_easy_getinfo(curl, CURLINFO_REUSED_CONNECTION, &reused_conn);
So if reused_conn == CURL_REUSED_TRUE: yes, re-used an already open
connection
else : no, it had to reconnect. (either directly or followed a location that
needed it)

I'm new to libcurl so I dont know where you want to put the information, ->
I used the struct PureInfo (could be in any other struct in data)

Tell me what you think ?

Note : I'm not sure but I expect that enum (int in theory) are long and not
short ?
