NAME

       curl_multi_add_handle - add an easy handle to a multi session

SYNOPSIS

       #include <curl/curl.h>

       CURLMcode curl_multi_add_handle(CURLM *multi_handle, CURL *easy_handle);

DESCRIPTION

       Adds a standard easy handle to the multi stack. This function call will make this multi_handle control the specified easy_handle.

       While  an  easy handle is added to a multi stack, you cannot and you must not use curl_easy_perform(3) on that handle. After having removed
       the easy handle from the multi stack again, it is perfectly fine to use it with the easy interface again.

       If the easy handle is not set to use a shared (CURLOPT_SHARE(3)) or global DNS cache (CURLOPT_DNS_USE_GLOBAL_CACHE(3)), it will be made	to
       use the DNS cache that is shared between all easy handles within the multi handle when curl_multi_add_handle(3) is called.

       When an easy interface is added to a multi handle, it will use a shared connection cache owned by the multi handle. Removing and adding new
       easy handles will not affect the pool of connections or the ability to do connection re-use.

       If  you	have  CURLMOPT_TIMERFUNCTION  set  in  the  multi  handle  (and  you  really   should	if   you're   working	event-based   with
       curl_multi_socket_action(3)  and  friends), that callback will be called from within this function to ask for an updated timer so that your
       main event loop will get the activity on this handle to get started.

       The easy handle will remain added to the multi handle until you remove it again with curl_multi_remove_handle(3) -  even  when  a  transfer
       with that specific easy handle is completed.

       You should remove the easy handle from the multi stack before you terminate first the easy handle and then the multi handle:

       1 - curl_multi_remove_handle(3)

       2 - curl_easy_cleanup(3)

       3 - curl_multi_cleanup(3)

RETURN VALUE

       CURLMcode type, general libcurl multi interface error code.
