I think what LI Xin was looking at is the return value of kevent(2) here. EPERM is the 1 in the last column.
Sorry, EPERM? Where do you see that? What does it mean.
From man intro(2):
1 EPERM Operation not permitted. An attempt was made to perform an operation limited to processes with appropriate privileges or to the owner of a file or other resources.
Looking at man kevent(2) there are a selection of errors that can be returned from this system call but EPERM isn't one of them.
Why would the 1 mean EPERM? See kevent()'s man page:
"The kevent() system call returns the number of events placed in the eventlist, up to the value given by nevents."
You are right. Sorry for confusion...
