Pass a NULL argument as prev to get the first option returned, or pass in the current option to get the next one returned. If there is no more option to return, curl_easy_option_next(3) returns NULL.
The options returned by this functions are the ones known to this libcurl and information about what argument type they want.
If the CURLOT_FLAG_ALIAS bit is set in the flags field, it means the name is provided for backwards compatibility as an alias.
