Subject: udev_device_get_sysattr_value upon device remove
Date: Fri, 03 Dec 2010 19:19:54 +0000 [thread overview]
Message-ID: <201012031319.54921.stefan.harjes@gmx.net> (raw)
Hi folks,
when I get an udev_device from the udev_monitor, because the device has been
unplugged, the 'udev_device_get_sysattr_value()' call returns 'null' (in my
case I was looking for the "serial" of an usb_device). From my understanding
this value should still be cached, even if the device is already removed?
Is there any other way to get this value?
Best
Stefan
