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.
