.SH NAME
|
||
|
|
curl_multi_setopt \- set options for a curl multi handle
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.nf
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLMcode curl_multi_setopt(CURLM *multi_handle, CURLMoption option, parameter);
|
||
|
|
.fi
|
||
|
|
.SH DESCRIPTION
|
||
|
|
\fIcurl_multi_setopt(3)\fP is used to tell a libcurl multi handle how to
|
||
|
|
behave. By using the appropriate options to \fIcurl_multi_setopt(3)\fP, you
|
||
|
|
can change libcurl's behavior when using that multi handle. All options are
|
||
|
|
set with the \fIoption\fP followed by the \fIparameter\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.
