Obtaining a CD image

[Alexander Frolkin <alexander@frolkin.demon.co.uk>]

Hello,

What is the correct way to get a CD image file under OpenBSD?

Under Linux, I can do

dd if=/dev/xxx of=cd_image

which works fine. Last time I tried this under OpenBSD (with xxx replaced by
cd0c), it didn't stop when it got past the end of the CD - the output grew
to over 1Gb.

What is the correct way to do this?

Thanks,
Alexander
