From ba410f6c64af26292d1dc549829c25af5602fbf7 Mon Sep 17 00:00:00 2001 From: Frank Gevaerts Date: Wed, 23 Nov 2016 10:44:18 +0100 Subject: add CURLINFO_SCHEME, CURLINFO_PROTOCOL, and %{scheme} Adds access to the effectively used protocol/scheme to both libcurl and curl, both in string and numeric (CURLPROTO_*) form. Note that the string form will be uppercase, as it is just the internal string. As these strings are declared internally as const, and all other strings returned by curl_easy_getinfo() are de-facto const as well, string handling in getinfo.c got const-ified.
