const struct curl_easyoption *curl_easy_option_by_id(CURLoption id);
Given a CURLoption id, this function returns a pointer to the curl_easyoption struct, holding information about the curl_easysetopt(3) option using that id. The option id is the CURLOPT prefix ones provided in the standard curl/curl.h header file. This function returns the non-alias version of the cases where there is an alias function as well.
If libcurl has no option with the given id, this function returns NULL.
int main(void)
{
const struct curl_easyoption *opt = curl_easy_option_by_id(CURLOPT_URL);
if(opt) {
printf("This option wants type %x\n", opt->type);
}

This function was added in libcurl 7.73.0
A pointer to the curl_easyoption struct for the option or NULL.
