To find out if the read pointer is currently pointing at
the mark in the data stream, the
.Fn sockatmark
function is provided. If
function is provided.
If
.Fn sockatmark
returns 1, the next read will return data
after the mark. Otherwise (assuming out of band data has arrived),
after the mark.
Otherwise (assuming out of band data has arrived),
the next read will provide data sent by the client prior
to transmission of the out of band signal. The routine used
to transmission of the out of band signal.
The routine used
in the remote login process to flush output on receipt of an
interrupt or quit signal is shown below.
It reads the normal data up to the mark (to discard it),
then reads the out-of-band byte.
