Hey, i used
Int16 Value = 1;
rc = NetLibSocketOptionSet (appNetRef, appSocketRef,
netSocketOptLevelSocket,netSocketOptSockNonBlocking, &optValueB,
sizeof(Value), 1, &rc);
once ane got 0 in rc that indicates no error, but still the connection is
blocking.....
Am i wrong somewhere ????

You only need to set a socket non-blocking once, using
NetLibSocketOptionSet(). You use NetLibSocketOptionSet() to prepare the socket
to send a notification as often as necessary.
A non-blocking socket will perfom the requested operation normally, if it can
complete without waiting. Otherwise, it will return an error (EWOULDBLOCK). For
example, it will not wait for received data, or wait for a connection to
complete, or wait for send buffers to become available. Be aware that socket
operations may be partial, meaning you could ask for 1000 bytes and get only
500, which means you'd need to keep reading until you get all you expect.

What is the way to use non bocking socket. Is there some parameter in API to
set or we have to do it manually by inserting delay ???
Jeff Loucks <[EMAIL PROTECTED]> wrote: If 'background' means in response to
a notification or alarm, then you are sharing the UI task. Are you doing a
BLOCKING read on the socket, waiting for data? If so, then the UI task is
blocked, and nothing else in the UI task will have time to work. Use
non-blocking sockets, so you don't hog the UI task. If you expect more data,
arrange to be called again at a later time, and give the UI task back to the
foreground.
