Sockets - lqNetDog and lqMiniTerm (req's libLQ)

Today's feature is:

lqNetDog and lqMiniTerm running sockets in a Qt gui.
C-style functions, Windows style conversion of slots to C funcs.
I/O in one terminal widget (still very simple).

Here's a screenshot.

Sockets - The NetDog mini-lib for socket connections

Today's feature is:

NetDog. :-)
A simple non-blocking ans (listen) and orig (connect) example.
Minor bundling of socket functions to greatly simplify a successful connection.

Complicating this stuff is easy. Simplifying it is the hard part.

The non-blocking setup here simplifies coding for a gui which needs to constantly be...

Sockets - A Packet Snooper With A QT4 GUI (Req's libLQ-qt/mc2 dload) Part 1

Today's feature is

Running a packet snooper in an lqMiniTerm 'run' loop function.

[Note: the lqMiniTerm is evolving a bit and will continue to evolve for a while as we experiment and discover things that come up over and over that are easier to address in the mini terminal than in the main() file's code.
