14 curl_multi_setopt(3) is used to tell a libcurl multi handle how to be‐
15 have. By using the appropriate options to curl_multi_setopt(3), you can
16 change libcurl's behavior when using that multi handle. All options are
17 set with the option followed by the parameter param. That parameter can
18 be a long, a function pointer, an object pointer or a curl_off_t type,
19 depending on what the specific option expects. Read this manual care‐
20 fully as bad input values may cause libcurl to behave badly. You can
21 only set one option in each function call.
