[SDL] A system monitoring daemon

[Nicola Larosa]

Hi everybody, and thanks for a great library (I use it via the Pygame
Python bindings).

I would like to write a daemon that monitors many different kinds of system
events, and uses those to build a representation of what goes on in the
system. (I'm actually more interested in an audio representation than a
visual one, but that's beside the point.)

Such a daemon should at the very least receive all user-generated events:
keys, mouse, joystick, touchscreen, audio input. It should also monitor the
main system parameters, like CPU usage, memory, block devices, network
traffic and so on.

SDL would be very handy for receiving the user-generated events: alas, the
daemon would need to always get them, without having a user interface and
being in focus. Is there a way to use SDL in such a fashion?

Also, what are the standard techniques to get the system-generated events?
I suspect that it would be difficult to write a portable daemon: I am
mainly interested in the Linux platform anyway.

of software. I've gone from gazing at record covers to gazing at
online help files, which is a little sick, now that I think about it.
