NAME
curl_multi_setopt - set options for a curl multi handle
SYNOPSIS
#include <curl/curl.h>
CURLMcode curl_multi_setopt(CURLM *multi_handle, CURLMoption option, param);
DESCRIPTION
curl_multi_setopt(3) is used to tell a libcurl multi handle how to
behave. By using the appropriate options to curl_multi_setopt(3), you
can change libcurl's behavior when using that multi handle. All options
are set with the option followed by the parameter param. That parameter
can be a long, a function pointer, an object pointer or a curl_off_t
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.
