Sorry, I meant C and C++ (research shows that even modern Linux kernels are mostly written in C, not C++)
Thanks for catching that typo.

curl_multi_add_handle
curl_multi_add_handle(3) libcurl Manual curl_multi_add_handle(3)
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.
