Sockets - Bidirectional Communication IPv4/6 (terminal version)

Posted 01-17-2013 at 08:54 PM by rainbowsally

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

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...

mini-term in qt4

mini-term in qt4.

Today's features:
  • A simple terminal-like application built from a qt4 class that can be used for other stuff too.
  • The present application can run shell commands and has copy/paste (ctrl-c, ctrl-v) capabilitity.
  • Another example of the Windows-like api so that C/C++ code can run in Qt4.
  • Runs the custom code (terminal in this case) inside a QT 'exec' loop... sorta. We call it 'run()'.

QT4 -- Having trouble with qInitResouces_<appname>() ?

Posted 01-14-2013 at 03:46 AM by rainbowsally

Having trouble with qInitResouces_<appname>()?

Try this.
Code:
#ifdef Q_INIT_RESOURCE
#undef Q_INIT_RESOURCE
#endif

#define Q_INIT_RESOURCE(name) extern void qInitResources_##name()
The version of this macro in qglobal.h could never have ever worked.

If you enjoy digging into the low level stuff, I think you'll be amused by the context of this bug. ;-)

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

Posted 01-13-2013 at 06:57 PM by rainbowsally

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,...
