There is one problem: I don't have a clue about how ioctl's in C or how to do them trough java. So i ask again, more precise this time: Is there any shell command i may run (etc) that will return this value? Or do i them have to either learn how to do ioctl's in Java, alternatively hack up some C program to do the ioctl? If i have to, i sense that this will be a long missing function (as its not really that important - but it migth be a good tool for the driver devs to get frequency offsets on new tuners - run this tool in frequency search mode with a small intervall, and post the results here (or somewhere), compare to "real" values) - learning all about ioctl's are not my number one priority... --- Kyrre _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
