Re: Reading binary file written by C program

I would start here:
http://raa.ruby-lang.org/search.rhtml?sea...
(Also, check on rubyforge.org)

You might want to look at Array#pack and String#unpack.
Also, make sure to open up the file as binary!

Enjoy.

in there you will see the binary-parse gem, I wrote it to do exactly
what you are describing for my own needs.

Remember how England used to be before the civil war and it ruled using the
church of England and Catholics got persecuted? Ok even you are probably to
young to remember that. My point is monarchy's using religion to control its
people are always bad news.

Civil rights. Apart from the Bahai's of course but are they any cases of
Christians being persecuted or killed in Iran?
