options: API for meta-data about easy options
const struct curl_easyoption *curl_easy_option_by_name(const char *name); const struct curl_easyoption *curl_easy_option_by_id (CURLoption id); const struct curl_easyoption * curl_easy_option_next(const struct curl_easyoption *prev); The purpose is to provide detailed enough information to allow for example libcurl bindings to get option information at run-time about what easy options that exist and what arguments they expect. THIS IS WORK IN PROGRESS, MEANT AS A DISCUSSION STARTING POINT. Not the final version.
