<div>A client would call gen_server:call(ircclient, {nick, ale}) to set the nickname for example.<br clear="all"></div><div>The "Erlang Way" is said to be to export actual functions (setnick, getnick, ...) from the gen_server module public API, and have those functions do the gen_server calls. This means that you can change the gen_server message format without breaking compatibility.</div>
<div> </div><div>Also, for synchronous calls (where you want the status), waiting the necessary amount of time is pretty much what you expect to do. You *can* make arrangements to use cast, and pass in a respond-to-PID parameter as part of the request, but in most cases, that adds significant extra complexity for very little benefit.</div>
<div> </div><div>Note that gen_server:call also takes a timeout parameter -- it defaults to 5,000 milliseconds, so if the gen_server is "wedged" then the timeout will kick in.</div><div> </div><div>Sincerely,</div>

Nevertheless, whether we get there willingly or not, we shall soon have lower consumption rates, because our present rates are unsustainable. <br>
