Hi,
this is what I have when fmradio applet is running and when I strace one of
the maemo-launcher processes:
...
open("/sys/devices/platform/gpio-switch/headphone/state", O_RDONLY) = 21
fstat64(21, {st_mode=S_IFREG|0644, st_size=4096, ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0x40002000
read(21, "disconnected\n", 4096) = 13
close(21) = 0
...
I think it happens each 2 sec or so.
What I meant before as /proc/something is actually /sys/something ;-)
cheers
Pit
