I just mentioned it, as Apple's mailing lists have a new [since I last was subscribed to these lists] option that defaults to not send my posts to the mailing list back to me.

You need someone more fluent in CF than me. My response was specifically for data buffered in the socket, but not yet sent to the other end. If the socket is async and it is not explicitly shutdown, then you will potentially lose unbuffered sent data. I actually can' imagine that the CFWriteStreamClose() would not flush output data before the close returned. If the socket was async, though, a real close (or the process exitting) won't be blocked, if the socket is async. Or is there another, better way to do this? Personally, I'd follow the PDF example exactly. It looks to me like it waits until everything has been sent. -- Terry I re-read the CFNetwork PDF, and I can't really follow the synchronous CFWriteStream sample as it's well, synchronous. The Close() is expected to be blocking, and should cause the data to be flushed. And of course the read stream sample is asynchronous, but also doesn't help with my specific situation, as there is no buffering involved [as the API should send all the data, then when the other side does an orderly disconnect, it passed the callback the remaining data, then sends is a 'stream has no more data' message, where the code then calls CFReadStreamClose(). I also searched Apple's sample code [cftpsample] and of course, it also does a network stream read, and a file stream write, so I wouldn't expect a problem there either. Since I register for a 'streamclosed' message, I'll see if I get one when I call writestreamclose() [and then release the streams]. _______________________________________________ Do not post admin requests to the list.
