Over zealous debugging :-) I only code c, so I have bad habbit's
already huh.

OK, what I want is NOT to count the \n so that I get output as such:

Snarfed:
Data aaaaa
Size 5

meaning I do not count the \n as output and I also loose the space
between Data and Size seen in my example. Basically stripping the new
line recieved from the server.

Only way I can think of doing it, keeping in mind I need to retain the
dynamic effect would be to use strstr() to find any instances and
remove it manually before passing it to fprintf. Any better methods to
achieve what I want?

I'm running the code agains a netcat listener on port 22 on my
workstation, that's all.
