.TH curl_multi_add_handle 3 "4 March 2002" "libcurl 7.9.5" "libcurl Manual"
.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);
.ad
.SH DESCRIPTION
Adds a standard easy handle to the multi stack. This function call will make
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
When an easy handle has been added to a multi stack, you can not and you must
not use \fIcurl_easy_perform(3)\fP on that handle!
2004-04-13 22:27:47 +08:00
2006-07-08 07:08:03 +08:00
If the easy handle is not set to use a shared (CURLOPT_SHARE) or global DNS
cache (CURLOPT_DNS_USE_GLOBAL_CACHE), 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.
If you have CURLMOPT_TIMERFUNCTION set in the multi handle (and you really
should), 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
.SH RETURN VALUE
CURLMcode type, general libcurl multi interface error code.
.SH "SEE ALSO"
.BR curl_multi_cleanup "(3)," curl_multi_init "(3)"
