/*
|
||||
* compile with:
|
||||
* gcc -o client client.c `pkg-config --cflags --libs eldbus ecore eina`
|
||||
*
|
||||
* This simple example connects to an IBus daemon running on the machine.
|
||||
* IBus daemon is a dbus daemon running apart from system or session buses.
|
||||
*
|
||||
* Requires ibus-daemon to be running, for instance:
|
||||
* $ ibus-daemon -v -r -s
|
||||
*
|
||||
* After starting ibus-daemon, check for its address on the file located on
|
||||
* ~/.config/ibus/bus/ directory. For instance:
|
||||
*
|
||||
* $ cat ~/.config/ibus/bus/809ee018614317e782464b8900000029-unix-0
|
||||
* # This file is created by ibus-daemon, please do not modify it
|
||||
* IBUS_ADDRESS=unix:abstract=/tmp/dbus-VOJaWARY,guid=e0082807a08a81ad22e0d3f551d48d5e
|
||||
* IBUS_DAEMON_PID=3697
|
||||
*
|
||||
* Export or set the IBUS_ADDRESS environment variable and run this program. To exit,
|
||||
* just hit ctrl+c
