For HTTP at least, What it doesn’t tell you is that you must keep calling it until you get the zero return value - otherwise you might not get the WIP_PEER_CLOSE event to tell you that the message body is complete!
The HTML sample in the WIP Development Guide only illustrates a simple GET; there needs to be at least another example showing a POST and the handling of sending both headers and a body…
Preferably, each available method would be illustrated - GET, HEAD, POST, and PUT.
