+    manual: Improve documentation of the shutdown function
+    
+    Document the SHUT_* constants and attempt to explain the

+    The Linux TCP behavior was discovered when writing the

++Additional errors can be reported for specific socket types.

++The exact impact of the @code{shutdown} function depends on the socket
++protocol and its implementation.  In portable code, the @code{shutdown}
++function cannot be used on its own to gracefully terminate a connection
++which is operated in full-duplex mode (with both peers sending data).
++
++On Linux, when @code{SHUT_RD} is used to shut down a TCP socket, any
++pending data in the incoming socket buffer and any data that arrives
++subsequently is discarded, without reporting an error or generating a
++TCP RST segment.  Attempts to read data from this socket using
++@code{recv} and similar functions (@pxref{Receiving Data}) return zero.
++(Other systems may treat @code{SHUT_RD} with pending data as a data loss
++event and generate RST segments.  Linux @code{AF_LOCAL}/@code{AF_UNIX}
++sockets also report errors to peers.)
++
++Similarly, when @code{SHUT_WR} is used on a Linux TCP socket, a FIN
++segment is sent to the peer, ordered after any data written previously
++to the socket.  After encountering the FIN segment, the peer will
++recognize this as an end-of-stream condition.
