[c++] read binary

-- 2007/06/19 bbs backup --
suppose there're codes

while(!foo.eof()){
    foo.getline(buf, num);
    // do someting
}

it works
but binary maybe take this style or it read more once



foo.read(buf, size);
while(!foo.eof()){
    // do something
    foo.read(buf, size);
}

On the last read cycle you still have a valid read, so eof() hasn't been
reached until you try and read past the last item. Try swapping your code
around slightly like in red above, it should work.
