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is no
longer valid.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
.
