This daemon was inspired by
- Christoph Bartelmus's lircd daemon
<http:http://www.lirc.org/>,
- Guus Sliepen's inputlircd daemon
<http://svn.sliepen.eu.org/inputlirc/trunk/>, and
- Julien Cristau's Xorg udev patch
<http://lists.x.org/archives/xorg-devel/2009-October/002797.html>.
The software's architecture is straight forward. At the center is monitor, which
monitors a list of file descriptors and calls the file descriptor's handler when
the file descriptor is "ready". Initially, lircd creates an lircd socket and
adds it to monitor's file descriptor list so that it can watch for lircd client
connection requests, and input creates a udev monitor and adds it to monitor's
file descriptor list so that it can watch for input event devices. When lircd
detects an lircd client connect request, it connects the client and adds it to
its client list so that it can send lircd messages to the client. When input
detects an input event device that is to be handled by eventlircd, it opens the
input device, creates a corresponding mouse/joystick event device (if needed)
and adds the input device to monitor's file descriptor list so that it can watch
for events. When input detects an event on one of its input devices, it performs
the key mapping and sends the resulting mapped event to either the lircd clients
or the input device's mouse/joystick event device depending on whether the
mapped event is a keyboard or mouse/joystick event.
The daemon (eventlircd) is a sysvinit daemon. While it should be compatible with
systemd, it is not a systemd daemon.
The software has no i18n or l10n.
