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.
