[maemo-developers] capturing key presses on N770

[From: Vinod Nanjaiah]

Frantisek, thanks a lot for your inputs.
This is the use case:
       I want to run a video streaming client in the foreground.
       In the background I want to run a process that captures the key presses and invokes a
       script to do something more.

I haven't yet had a peek at the evkey.c and bootmenu.sh - hope this is it.

Thank you,
Vinod

Not sure what is the scenario you want to use it for. For low level
access you can use kernel input subsystem directly

see e.g. evkey.c [1] and its usage in bootmenu.sh [2]. Just beware that
different devices have different device names and key events still go to
the rest of the system.

For playing nice with the system using powerlaunch [3] is indeed better.
I am not aware of 770 version (the author [4] has/had N800) but the
source is here [4]. Maybe it could build fine at least in OS2007 hacker
edition.
