request realtime delay on output
Sent to a media driver to request a realtime delay on output.
The data buffer associated with this message type
is expected to contain an integer
to indicate the number of machine ticks of delay desired.
M_DELAY messages are typically used
to prevent transmitted data from exceeding
the buffering capacity of slower terminals.
The message format is not defined by STREAMS,
and its use is developer-dependent.
Not all media drivers may understand this message.
This message can be considered
a special case of an M_CTL message.
An M_DELAY message
cannot be generated by a user-level process
and is always discarded if passed to the Stream head.
