curl_easy_option_by_name - find an easy setopt option by name

Added in curl 7.73.0

Given a name, this function returns a pointer to the curl_easyoption struct, holding information about the curl_easy_setopt(3) option using that name. The name should be specified without the CURLOPT_ prefix and the name comparison is made case insensitive. If libcurl has no option with the given name, this function returns NULL.

int main(void) { const struct curl_easyoption *opt = curl_easy_option_by_name("URL"); if(opt) { printf("This option wants CURLoption %x\n", (int)opt->id); } }
