You will receive only one socket notice for each
NetLibSocketOptionSet(...,netSocketOptSockNotice,...) call. In other words,
the socket clears your notice information after sending the notice. You can
configure the socket to send the next notice, while you are processing the
current notice. Note, that you only register for the notification once, but
you set up the socket every time you need a notice sent.
Since the only implemented notice type is 'Notification', there is a chance
that additional socket activity has occured between the time the socket sent
the notification and the time your application receives the notification.
That means you must be careful to use the notice as a suggestion that the
socket needs attention, and then fully service the socket in response to
each notice.
The original socket notice was a procedural callback, which synchronized the
socket with the socket consumer, and allowed determinant socket services. A
notice via notification is sloppy, but with care, can get the job done.
