</span>We are using a pool of accept sockets; but I would have thought that<br>
the fact that we've been around the loop and set {active, once} before<br>
this happens means that we're not getting bitten by this?<br>

</span>We are using {active, once}; can you point to an example of an OTP<br>
application that handles messages across multiple packets? I'm pretty<br>
sure that I can sort this out by using {active, true} and using<br>
selective receive, but I'd like to see an example with {active, once}.<br></blockquote><div><br></div><div><br></div><div>The ssl application uses active once internally (the active once on an sslsocket is emulated), so does the ssh application and inets</div><div>HTTP-server to name a few.</div><div><br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">

</span>Surely that's {active, true}, or am I missing something?<br></blockquote><div><br></div><div>Active once (or nowdays even active N) can be used to get some flow control as opposed to active mode.</div><div><br></div><div>Regards Ingela Erlang/OTP Team - Ericsson AB </div></div></div></div>
