- socket-abandon-port portprocedure
Marks the socket input or output port port as abandoned. Normally, when an socket input port is closed the read side of the connection is shut down; similarly closing the output port shuts down the write side. Marking a port as abandoned skips this shutdown. This is useful to ensure a connection stays open after the port is closed.
The socket is still closed after both ports are closed, regardless of their abandoned status.
