NAME
       curl_easy_perform - Perform a file transfer

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_perform(CURL *handle);

DESCRIPTION
       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 fol-
       lowing 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 transfers, 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.

RETURN VALUE
       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 message  in  the  error
       buffer when non-zero is returned.

BUGS
       Surely there are some, you tell me!
