       curl_easy_perform - Perform a file transfer

       #include <curl/curl.h>

       CURLcode curl_easy_perform(CURL *handle);

       This  function is called after the init and all the curl_easy_setopt() calls are made, and
       will perform the transfer as described in the options.  It must be called  with	the  same
       handle as input as the curl_easy_init call returned.

       libcurl	version  7.7  or  later  (for older versions see below): You can do any amount of
       calls to curl_easy_perform() while using the same handle. If you intend to  transfer  more
       than  one  file, you are even encouraged to do so. libcurl will then attempt to re-use the
       same connection for the following transfers, thus making the operations faster,	less  CPU
       intense	and  using  less  network  resources.  Just  note  that  you  will  have  to  use
       curl_easy_setopt between the invokes to set options for the following curl_easy_perform.

       You must never call this function simultaneously from two places using  the  same  handle.
       Let the function return first before invoking it another time. If you want parallel trans-
       fers, you must use several curl handles.

       Before libcurl version 7.7: You are only allowed to call this function once using the same
       handle.	 If  you  want	to  do	repeated  calls,  you  must  call  curl_easy_cleanup  and
       curl_easy_init again first.

       0 means everything was ok, non-zero means an error occurred as <curl/curl.h>  defines.  If
       the  CURLOPT_ERRORBUFFER was set with curl_easy_setopt there will be a readable error mes-
       sage in the error buffer when non-zero is returned.

       curl_easy_init(3), curl_easy_setopt(3),

       Surely there are some, you tell me!
