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.

TIMES

       An overview of the six time values available from curl_easy_getinfo()

       curl_easy_perform()
           |
           |--NAMELOOKUP
           |--|--CONNECT
           |--|--|--APPCONNECT
           |--|--|--|--PRETRANSFER
           |--|--|--|--|--STARTTRANSFER
           |--|--|--|--|--|--TOTAL
           |--|--|--|--|--|--REDIRECT

       NAMELOOKUP
              CURLINFO_NAMELOOKUP_TIME and CURLINFO_NAMELOOKUP_TIME_T.  The time it took from the
              start until the name resolving was completed.

       CONNECT
              CURLINFO_CONNECT_TIME and CURLINFO_CONNECT_TIME_T.  The time it took from the start
              until the connect to the remote host (or proxy) was completed.

       APPCONNECT
              CURLINFO_APPCONNECT_TIME and CURLINFO_APPCONNECT_TIME_T.  The time it took from the
              start until the SSL connect/handshake with the remote host was completed. (Added in
              7.19.0)  The  latter  is  the  integer version (measuring microseconds).  (Added in
              7.60.0)

       PRETRANSFER
              CURLINFO_PRETRANSFER_TIME and CURLINFO_PRETRANSFER_TIME_T.  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 particular  protocol(s)
              involved.

       STARTTRANSFER
              CURLINFO_STARTTRANSFER_TIME  and  CURLINFO_STARTTRANSFER_TIME_T.   The time it took
              from the start until the first byte is received by libcurl.

       TOTAL  CURLINFO_TOTAL_TIME and CURLINFO_TOTAL_TIME_T.  Total time of the previous request.

       REDIRECT
              CURLINFO_REDIRECT_TIME and CURLINFO_REDIRECT_TIME_T.  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 redirection took place.

RETURN VALUE

       If the operation was successful, CURLE_OK is returned. Otherwise an appropriate error code
       will be returned.
