Hi markp,

Suppose your buffer is My_Buffer, and after the first call you see
Last < My_Buffer'Last (note that if Last < My_Buffer'First then the
connection has gone down).  Then you can do the following:

   procedure Receive_Socket
     (Socket => My_Socket,
      Item   => My_Buffer (Last + 1 .. My_Buffer'Last),
      Last   => Last);

GNAT.Sockets provides higher level routines - the stream stuff.

Ciao,

Duncan.
