pass file pointer between Stream heads
This message type is used by STREAMS
to pass a file pointer from the Stream head
at one end of a Stream pipe
to the Stream head at the other end of the same Stream pipe.
(A Stream pipe is a Stream
that is terminated at both ends by a Stream head;
one end of the Stream can always find the other by following the
q_next pointers in the Stream.
The means by which such a structure is created are
not described in this document.)
The message is generated as a result of an
issued by a process to the sending Stream head.
The only devices that allow this message to be passed
are loopback-style STREAMS devices
where both ends of the Stream are Stream heads.
In other words, both ends are user-level programs
rather than devices.
the STREAMS pipe driver,
Note that a
system call returns a pipe that consists of a Stream,
but it does not allow this message.
