.TH curl_multi_setopt 3 "8 Jan 2006" "libcurl 7.16.0" "libcurl Manual"
|
|
.SH NAME
|
|
curl_multi_setopt \- set options for a curl multi handle
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLMcode curl_multi_setopt(CURLM * multi_handle, CURLMoption option, param);
|
|
.SH DESCRIPTION
|
|
curl_multi_setopt() is used to tell a libcurl multi handle how to behave. By
|
|
using the appropriate options to \fIcurl_multi_setopt\fP, you can change
|
|
libcurl's behaviour when using that multi handle. All options are set with
|
|
the \fIoption\fP followed by the parameter \fIparam\fP. That parameter can be
|
|
a \fBlong\fP, a \fBfunction pointer\fP, an \fBobject pointer\fP or a
|
|
\fBcurl_off_t\fP type, depending on what the specific option expects. Read
|
|
this manual carefully as bad input values may cause libcurl to behave badly!
|
|
You can only set one option in each function call.
|
|
|
|
.SH OPTIONS
|
|
.IP CURLMOPT_SOCKETFUNCTION
|
|
Pass a pointer to a function matching the curl_socket_callback prototype. The
|
|
\fIcurl_multi_socket(3)\fP functions inform the application about updates in
|
|
the socket (file descriptor) status by doing none, one or multiple calls to
|
|
the curl_socket_callback given in the \fBparam\fP argument. They update the
|
|
status with changes since the previous time a \fIcurl_multi_socket(3)\fP
|
|
function was called. If the given callback pointer is NULL, no callback will
|
|
be called. Set the callback's fourth argument with \fICURLMOPT_SOCKETDATA\fP.
|
|
See \fIcurl_multi_socket(3)\fP for more callback details.
|
|
.IP CURLMOPT_SOCKETDATA
|
|
Pass a pointer to whatever you want passed to the curl_socket_callback's forth
|
|
argument, the userp pointer. This is not used by libcurl but only passed-thru
|
|
as-is. Set the callback pointer with \fICURLMOPT_SOCKETFUNCTION\fP.
|
|
.SH RETURNS
|
|
The standard CURLMcode for multi interface error codes. Note that it returns a
|
|
CURLM_UNKNOWN_OPTION if you try setting an option that this version of libcurl
|
|
doesn't know of.
|
|
.SH AVAILABILITY
|
|
This function was added in libcurl 7.15.4.
