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, parameter);

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. 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.

       you try setting an option that this version of libcurl does not know of.
