.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, 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\(aqs 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.
