Sockets - Bidirectional Communication IPv4/6 (terminal version)

Today's features:

More fun with sockets.
Bidirectional communication using IPv4 and IPv6 socket streams (sequential).
Interactive. (Only interprets one command, but it's easily expandable.)
Terminal version for broader usefulness.

[Note the addresses in this and the previous sockets experiments (here http://www.linuxquestions.org/questi...example-35270/)...

Sockets - UDP RX (recieve/transmit) terminal example
Today's feature:

A UDP file server and client using linux sockets.
A terminal app for those who don't have libLQ-qt and mc2.

[This is for our LQ-less friends. A libLQ version using a qt gui but NOT qt sockets should be forthcoming shortly.]

This upload is pushing the size limit but it's interesting to see how the broadcast channel is set up (in inc/broadcast-rx.c) and how the parts of the files are picked up...

Simple C example for beginners and bug fix for libLQ-qt version 3.0.x

[v.3.0 (mc2 and libLQ) will no longer be the current version(s) but it still works and we have a bug fix here that applies to all 3.0.x versions.]

Today's feature:

A simple C/C++ example.
A converter from relative paths to absolute.
A bug fix for the libLQ-qt/mc2 3.0 d/load.

While 'canonicalize_file_name()' is great for paths that don't have macros in them, and for dereferencing symlinks,...

Parser Test 3 (A Return Stack & Compiler)

A self extractor for the 'lib' files that we include for this (pretty cute) little calculator are here.
http://www.linuxquestions.org/questi...wsally-615861/

Re: the compiler part. It's not much of a compiler, but it serves as a proof of concept. (It's used internally, the program is not compiled.)

Before we dig in here, I should say...

Bug in Parser Test 2.

Parser Test 1

------------------------------------

See the previous blog entry: "Playing with parsing" here.
http://www.linuxquestions.org/questi...wsally-615861/
to grab the files we need to include for these tests and a working mc2 definitions file for those who have mc2. Type "mc2 -init" first time. After that "make update" will add/remove files from the makefile.

[Note that we can link OR include...
