Hi,
as shown in SampleURLConnection, I created a CFWriteStreamRef using a
CFSocket previously created and connected to the server and configured
with
CFSocketSetSocketFlags(sock, kCFSocketAutomaticallyReenableWriteCallBack);
CFSocketEnableCallBacks(sock, kCFSocketWriteCallBack);
event though there is no Write callback defined at socket level.
Then I bound it to my WriteStream with CFStreamCreatePairWithSocket
set a delegate with CFWriteStreamSetClient and scheduled the Write
Stream on the runloop.
It works except that the callback only works for the first event
(kCFStreamEventOpenCompleted). After, it is like disabled.
right before I tried with a CFSocket directly and setting the
kCFSocketAutomaticallyReenableWriteCallback flag fixed this behaviour.
Should I use something else when at WriteStream level?
Thank you very much.
