- We could let the user drive the underlying libevent event loop in
- three different ways, from easiest to hairiest:
-
- i) Blocking i/o model: User passes NULL for the callbacks in
- rs_conn_open() and the open, send and receive calls will block
- until the wanted event occurs. Other events occurring while
- waiting will be either silently discarded or signaled as an error
- (f.ex. broken connection while sending).
-
- ii) Simple interface with a timeout: User calls
- rs_event_loop(timeout) to process pending i/o.
-
- iii) full libevent interface: TODO.
