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(3) 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.

       You  can  do  any  amount  of calls to curl_easy_perform(3) 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(3) 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 transfers, you must use several curl
       handles.

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.
