NAME
curl_easy_getinfo - extract information from a curl handle
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *curl, CURLINFO info, ... );
DESCRIPTION
Request internal information from the curl session with this function.
The third argument MUST be a pointer to a long, a pointer to a char *,
a pointer to a struct curl_slist * or a pointer to a double (as this
documentation describes further down). The data pointed-to will be
filled in accordingly and can be relied upon only if the function
returns CURLE_OK. Use this function AFTER a performed transfer if you
want to get transfer related data.
You should not free the memory returned by this function unless it is
explicitly mentioned below.

|--NAMELOOKUP
|--|--CONNECT
|--|--|--APPCONNECT
|--|--|--|--PRETRANSFER
|--|--|--|--|--STARTTRANSFER
|--|--|--|--|--|--TOTAL
|--|--|--|--|--|--REDIRECT
NAMELOOKUP
CURLINFO_NAMELOOKUP_TIME. The time it took from the start until
the name resolving was completed.
CONNECT
CURLINFO_CONNECT_TIME. The time it took from the start until the
connect to the remote host (or proxy) was completed.
APPCONNECT
CURLINFO_APPCONNECT_TIME. The time it took from the start until
the SSL connect/handshake with the remote host was completed.
(Added in in 7.19.0)
PRETRANSFER
CURLINFO_PRETRANSFER_TIME. The time it took from the start until
the file transfer is just about to begin. This includes all pre-
transfer commands and negotiations that are specific to the par-
ticular protocol(s) involved.
STARTTRANSFER
CURLINFO_STARTTRANSFER_TIME. The time it took from the start
until the first byte is received by libcurl.
TOTAL CURLINFO_TOTAL_TIME. Total time of the previous request.
REDIRECT
CURLINFO_REDIRECT_TIME. The time it took for all redirection
steps include name lookup, connect, pretransfer and transfer
before final transaction was started. So, this is zero if no re-
direction took place.
RETURN VALUE
If the operation was successful, CURLE_OK is returned. Otherwise an
appropriate error code will be returned.
