.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
\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 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.
