[PD] Reading and writing binary files

[David]

It's probably very obvious, but I can't figure out how to read and
write files containing arbitrary binary data. I know there are objects
for reading and writing sound files, and there's [textfile] for
reading text files, but I want to read and write binary files, and
interpret each byte as a 16-bit integer. Does anyone have an example I
can look at? Since they will be small files, I just need to read them
sequentially, I don't need to jump around in the file randomly.
