Ok, so I've already found out that Mathlink can't handle
IEEE 80-bit floats on Intel (due to a bug that Wolfram
So I hacked up a crude way of transferring data using
the BinaryFile package in Utilities. Unfortunately,
on DOS/Windows, this isn't a real binary file interface,
because the OpenFile builtin function that gets called
doesn't actually open the file as binary.
So, if the binary data in the file contains a byte that
just happens to equal the DOS eof character (hex 1a,
decimal 26 - please, please, don't get me started on Microsoft
toy OSes), the read returns EOF instead of the number.
Does anyone know of a workaround that will allow me to
actually read binary files on the Windows platform?
Thanks in advance. By the way, if I can get this to
work, I will post my enhanced version of the binary
files package that supports little-endian/long doubles.
