lirc_client library offers a simple access to IR for applications.
See: http://www.lirc.org/html/technical.html#library

In a lircrc file you write things like:
If the button MUTE of  the STRANGE remote is pushed,
I want the PLAYER application to retrieve the string "Shut up!" in a 
simple way.
begin
  button = MUTE
  remote = STRANGE
  prog = PLAYER
  config = Shut up!
end
See: http://www.lirc.org/html/configure.html#lircrc_format.

Yes.
Your get_ircode() will read from IR device with lirc_nextcode().
The call is blocking. Your application will wait for IR.
You get a code then.
You use it with lirc_code2char() to get the config string you have 
written in lircrc.

The same value you put in your lircrc.

etc? If the problem is etc, the solution will be of the same brand: etc.
What was the command line?
Show your /etc/lircd.conf.
Is the LIRC you installed working?

You need one. lirc_client library works with it.

These are real:
tools/ircat.c, tools/irexec.c, tools/irpty.c or tools/irxevent.c.
