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 <a Class="emphasis" href="./curl_easy_setopt.html">curl_easy_setopt</a> between the invokes to set options for the following curl_easy_perform.
<p class="level0">You must never call this function simultaneously from two places using the same <span Class="bold">easy_handle</span>. Let the function return first before invoking it another time. If you want parallel transfers, you must use several curl easy_handles.
