Oh, I didn't understand that. Thanks for pointing that out.

Yes, that was one of the problems.

The other problem right now is that I don't understand how to get the
32-bit messageflags from the file? I know how to read info line by
line from textfiles, but I don't understand how to read the file and
get the 32-bits from it? I don't understand the difference between
textfiles and binary files...
