(it just writes to stdout at the moment) Yeah, you'll probably want a struct similar to the JSON output from /metadata in Shindig. As a library user / module writer, that's what I'd want to consume. Definitely try libcurl in multi mode -- it's quite possible to implement a high concurrency http client in this model using async events -- you can use libevent for this. The ideal library would probably look something like this: os_request *req = os_request_create(); req->locale = ... os_request_add_gadget(req, "http://example.org/gadget.xml";); os_get_data(req, &callback); void callback(os_request *req, os_response *resp) {...} Rendering could then be implemented as a consumer of this library. > > thanks to all, > leonardo >
