If use truss on an oracle process. we could see something like the
following,  so semtimedop should be a syscall

22459/1: semtimedop(9, 0xFFFFFD7FFFDFE648, 1, 0xFFFFFD7FFFDFE488) EAGAIN
22459/1:         semnum=15    semop=-1    semflg=0
22459/1:         timeout: 2.060000000 sec


but the following command shows nothing. How can I trace semtimedop using
dtrace ?
 dtrace -l|grep semtimedop

Thanks,
Daniel
