lqNetDog Addon For Experimenters

Today's feature is
  • An addon for netdog-v1.2 to get and set connection properties.
  • Setting the blocking timout for the receiver (ans).

Remember, 'ans' (accept) needs to be online to receive the 'orig'inating connection, just like with a phone. Someone has to be there to accept the call or you'll never 'connect'.

We're currently simplifying sockets by combining two or three related functions in a single call using a common...

Sockets - The Black Box

Posted 01-23-2013 at 09:44 AM by rainbowsally

Today's feature:
  • A simple sockets debugging exercise.

Relax. It actually IS simple. You'll see.

You probably wouldn't be reading this if you didn't know how hard it is to find decent, simple example code.

Me too! And so there have been a few missteps in the previous entries (though they are adequate as demos), but it's all starting to shape up.

Yuh know, all I personally needed was a way to communicate between application so I could do stuff...

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 lqNetDog mini-lib for socket connections

Posted 01-22-2013 at 06:40 AM by rainbowsally
Updated 01-22-2013 at 10:52 AM by rainbowsally (moved some includes)

[Bad logic level in netdog_request() presumably fixed. -rs]

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...

Working with my good friend Christoph (he did all the hard stuff I just tested) we got my Pi Camera to work properly as a service and display the page embedded in a html page for internet viewing. All works well!
