Hmmm.... I suppose that all depends on the c library used to compile and how IT
determines the end of a binary file. Properly, if you open a file as binary and
process if until eof, then the system should not let you process beyond the end
of it. I've never had a problem of reading beyond an end of file on a Windows
system, but I've never use Micros*fts Visual C Run Time Library.
As far as I know the system and CRTL should properly report and end of file
whether you open and binary or text mode no matter what the actual fiel type is
on the system.
If you want me to test some stuff I've got a Windows NT system and MS Visual C++
6.0 to compile it with.
