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 behave. By using the appropriate options to curl_multi_setopt(3), you can change libcurl's behaviour 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.
