Hey, I just tried it on an xemacs process on S10 11/06:
$ truss -v poll -p 16332
pollsys(0xFFBFE140, 4, 0xFFBFE208, 0x00000000) (sleeping...)
fd=3 ev=POLLRDNORM rev=0
fd=7 ev=POLLRDNORM rev=0
fd=8 ev=POLLRDNORM rev=0
fd=9 ev=POLLRDNORM rev=POLLOUT
timeout: 19.998941000 sec
Hmm, that's pollsys, which is the system call that eventually gets
called by the poll libc routine. Truss appears to parse struct pollfd
for pollsys, at any rate.
