Public = ConnFD.T OBJECT
fd : INTEGER;
closed: BOOLEAN := FALSE;
END;
The type Public reveals enough structure of the POSIX implementation
of TCP.T to allow a client to perform operations directly upon the
POSIX file descriptor in fd. If closed is TRUE, then fd is no
longer valid. Any operations on fd must be performed with the
object's mutex locked and the caller should assert that closed is
FALSE.
