curl_multi_setopt(3) libcurl Manual curl_multi_setopt(3)
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 be-
have. 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 care-
fully as bad input values may cause libcurl to behave badly. You can
only set one option in each function call.
