Especially after I mentioned in this thread the man page example for 
getaddrinfo used memset.

More than 5 years ago we ere trying you to teach you the aspects of 
ponters but you have learned nothing abount.

Now the time is comed for you to see that you are always unable to learn 
programming anyway. Give up any try now. It is hopeless for you.

    You know they say "If at first you don't succeed try try again." Don't 
be lilly livered. This might take 20 years. A lifetime. I really don't care. 
I have my goal. I don't know the meaning of the word "hopeless". Don't tell 
me I haven't learned anything. I can't and don't need to demonstrate to you 
that I have. I know I have. I know the world's coming to an end blah blah. 
Fuck if I gave up now. All would be in vain. I have gave up on kandr2 
though. Just not the right book. Now I don't expect to become a professional 
computer programmer no. That I know I can't do. But I can learn to work with 
a few APIs.

    Don't try to teach. You just lend a hand you'll stress yourself out your 
patience is a nanometer long.

    That's cumed. Not comed.

Tell me are you as stupid and blind to obvious leg pulling in the real
world? "We" have not been trying to teach Bill for years. Only idiots
who dont realise they are being trolled. It *really* is that
clear. There is *no* room for doubt.

Pretty sure?  Can't you read what it actually says?
