Hi all,
There are two ways of closing a TCP socket. One is to use "close", and the other is to use "shutdown". The later allows half-closed sockets (i.e. - one side is closed, the other still open), which is a bonus. However, the info page for shutdown states that closing the write part (i.e. - saying you won't send any more data) will discard any unsent data. This is a problem when using asynchronous mode. The only workaround that pops to mind is to use fsync, which is blocking and thus unsuitable.
Anyone have any idea how to solve this problem? I need an asynchronous way of knowing when it is ok to call "shutdown" without losing information sent to the socket.
