fslogger : ioctl error : Bad Address

Question

I'm using this fslogger.c to get File System Notifications in my Mac. But it works only in Leopard & SnowLeopard, not in Lion or Mountain Lion.

when trying to clone the /dev/fsevents using ioctl it returns the error number 14(Bad Address). I have tried fixing it,i thought it could be some issues in ioctl function arguments. So i have tried modifying that, but no use at all. I couldn't get that fixed at all. Any idea how to make it work for Lion & Mountain Lion.

Answer 1

From Lion Onwards, the Security has been increased. So i have to open the file with a Third argument "S_IROTH". That will give access to /dev/fsevents device stream. Hope this is helpful to someone like me.
