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
       _multi_setopt&section=3">curl_multi_setopt(3) is used to tell a libcurl multi handle how to
       behave. By using the appropriate options to _multi_setopt&section=3">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.
