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.
