You want to monitor changes in system state and you do not really want to monitor myriad of devices but just latch onto one data feed and get all the data from it (unlike input devices where you might want to separate data coming from different devices). The following "event" might be a good starting point: struct system_change_event { struct timeval time; /* look for 32/64 bit issues */ __u16 type; __u16 code; __s32 value; char object_path[224]; }; Maybe we should start looking into connector or a pure netlink implementation. -- Dmitry |
