I made a mistake and opened a binary file using fopen("file","r"). Note that 
I forgot to open it with "rb". When I read the file, I could only read part
of the file: the read only suceeded for 2081 bytes of the 345K! Believing
that I had made a coding mistake, I tried 'wc'. It agreed with my code: they 
both 'think' the file has 2081 bytes. However emacs and ls both realize the
file is much larger. (When I used a truly ascii file, the size worked
correctly. The code hack does work correctly under the Metrowerks compiler.)

Does this seem like the correct behaviour? I can't trust wc because it
obviously opens as text. I looked in the faq without seeing anything that
suggests this operation. In this case the failure was the best thing that
could have happened because I discovered that the legacy unix code needs
some work around the binary/text problems. 

PS. I have the binary file which exhibits this problem if anyone is
interested.
