It actually has little to do with C++/C and may have more to do with the
programming model using an event loop. Essentially, when you have an
eventloop then everything is done via callbacks which are triggered as a
function of some event. In the case of the default libwww eventloop, the
events are caused by socket interactions, like a socket is ready for
reading, etc.
