This is just a simple reader which uses epoll on Linux, this is currently being used to read from simple character devices in linux. It also intended as a experiment for those interested in messing around with syscalls in golang.
Why can't we just use the normal file reader in golang?
Because some very basic character devices don't implement all the neccessary calls to support it.
func lineHandler(buf []byte, n int) {
log.Printf("data % X", buf)
}
func main() {
if err := epoller.OpenAndDispatchEvents("/dev/kmsg", lineHandler); err != nil {
log.Fatalf("Error opening device reader %v", err)
}
