.SH NAME
|
|
|
|
|
curl_multi_add_handle - add an easy handle to a multi session
|
|
|
|
|
.SH SYNOPSIS
|
|
|
|
|
#include <curl/curl.h>
|
|
|
|
|
|
|
|
|
|
CURLMcode curl_multi_add_handle(CURLM *multi_handle, CURL *easy_handle);

.SH DESCRIPTION
|
2004-03-15 19:37:37 +08:00
|
|
|
Adds a standard easy handle to the multi stack. This function call will make
|
2013-08-10 05:27:43 +08:00
|
|
|
this \fImulti_handle\fP control the specified \fIeasy_handle\fP. Furthermore,
|
|
|
|
|
libcurl now initiates the connection associated with the specified
|
|
|
|
|
\fIeasy_handle\fP.
|
2002-03-07 16:50:18 +08:00
|
|
|
|
2014-02-18 15:29:39 +08:00
|
|
|
While an easy handle is added to a multi stack, you can not and you must not
|
|
|
|
|
use \fIcurl_easy_perform(3)\fP on that handle. After having removed the handle
|
|
|
|
|
from the multi stack again, it is perfectly fine to use it with the easy
|
|
|
|
|
interface again.
|
2004-04-13 22:27:47 +08:00
|
|
|
|
2014-06-22 02:21:47 +08:00
|
|
|
If the easy handle is not set to use a shared (\fICURLOPT_SHARE(3)\fP) or
|
|
|
|
|
global DNS cache (\fICURLOPT_DNS_USE_GLOBAL_CACHE(3)\fP), it will be made to
|
|
|
|
|
use the DNS cache that is shared between all easy handles within the multi
|
|
|
|
|
handle when \fIcurl_multi_add_handle(3)\fP is called.
|
2006-07-08 07:08:03 +08:00
|
|
|
|
2013-08-10 05:27:43 +08:00
|
|
|
If you have CURLMOPT_TIMERFUNCTION set in the multi handle (and you really
|
2013-08-10 05:53:51 +08:00
|
|
|
should if you're working event-based with \fIcurl_multi_socket_action(3)\fP
|
|
|
|
|
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.
|

|
|
|
|
2004-04-13 22:27:47 +08:00
|
|
|
The easy handle will remain added until you remove it again with
|
|
|
|
|
\fIcurl_multi_remove_handle(3)\fP. You should remove the easy handle from the
|
|
|
|
|
multi stack before you terminate first the easy handle and then the multi
|
|
|
|
|
handle:
|
|
|
|
|
|
|
|
|
|
1 - \fIcurl_multi_remove_handle(3)\fP
|
|
|
|
|
|
|
|
|
|
2 - \fIcurl_easy_cleanup(3)\fP
|
|
|
|
|
|
|
|
|
|
3 - \fIcurl_multi_cleanup(3)\fP
|
2002-03-04 18:09:48 +08:00
