How does one read in simple binary files? [message #5550]

This is an incredibly basic question: what's the simplest way
to read in a simple binary file (ie an file of 16384 2-byte integers
representing a 128x128 pixel image, for example), or slightly
more complicated binary files (an array of 16384 IEEE 32-bit reals
with a 100-byte header preceeding the pixel values, for example.)
Are there any standard packages/routines for handling this kind of i/o,
with or without byte and word swapping? All
I can find in the manuals are routines for reading in ascii text, or
various specialized formats, but nothing generic. Does "unformatted i/o"
(readu, etc.) do this sort of input?

Thanks,
