curl_easy_getinfo  -  Extract information from a curl ses­
       sion (added in 7.4)


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 * 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.  This function
       is  intended to get used *AFTER* a performed transfer, all
       results from this function are undefined until the  trans­
       fer is completed.


AVAILABLE INFORMATION

       These are informations that can be extracted:

       CURLINFO_EFFECTIVE_URL
               Pass  a  pointer to a 'char *' to receive the last
               used effective URL.

       CURLINFO_HTTP_CODE
               Pass a pointer to  a  long  to  receive  the  last
               received HTTP code.

       CURLINFO_FILETIME
               Pass  a  pointer  to  a long to receive the remote
               time of the retrieved document. If you get  0,  it
               can  be  because  of  many  reasons  (unknown, the
               server hides it or the server doesn't support  the
               command that tells document time etc) and the time
               of the document is unknown. (Added in 7.5)

       CURLINFO_TOTAL_TIME
               Pass a pointer to a double to  receive  the  total
               transaction  time  in  seconds  for  the  previous
               transfer.

       CURLINFO_NAMELOOKUP_TIME
               Pass a pointer to a double to receive the time, in
               seconds,  it  took  from  the start until the name
               resolving was completed.

       CURLINFO_CONNECT_TIME
               Pass a pointer to a double to receive the time, in
               seconds,  it took from the start until the connect
               to the remote host (or proxy) was completed.

               Pass a pointer to a double to receive the time, in
               seconds,  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.

       CURLINFO_SIZE_UPLOAD
               Pass a pointer to a double to  receive  the  total
               amount of bytes that were uploaded.

       CURLINFO_SIZE_DOWNLOAD
               Pass  a  pointer  to a double to receive the total
               amount of bytes that were downloaded.

       CURLINFO_SPEED_DOWNLOAD
               Pass a pointer to a double to receive the  average
               download speed that curl measured for the complete
               download.

       CURLINFO_SPEED_UPLOAD
               Pass a pointer to a double to receive the  average

       CURLINFO_HEADER_SIZE
               Pass a pointer to a long to receive the total size
               of all the headers received.

       CURLINFO_REQUEST_SIZE
               Pass a pointer to a long to receive the total size
               of the issued requests. This is so  far  only  for
               HTTP requests. Note that this may be more than one
               request if FOLLOWLOCATION is true.

       CURLINFO_SSL_VERIFYRESULT
               Pass a pointer to a long to receive the result  of
               the  certification verification that was requested
               (using  the   CURLOPT_SSL_VERIFYPEER   option   to

       CURLINFO_CONTENT_LENGTH_DOWNLOAD
               Pass a pointer to a double to receive the content-
