Well, perhaps Alan should post a message to the list describing exactly what he's looking for?
My personal belief is that /dev/dpty is trying to address little parts of too many problems. The 256-minors problem exists, and should be addressed head-on (64-bit kdev_t or devfs) instead of hacked around in a different manner for every device.
Should I implement a syscall that gives me a fd for the 257th disk partition device, or for th 257th serial port?

Quite a claim. Perhaps you'd like to explain your security policy in more detail?

I hardly think Solaris 'isn't entrenched enough to be worth much'. xterm, for example, has had code to support Unix98/Solaris-style pty allocation since at least 1995. I suspect the vast majority of portable applications to be similar. --Scott @ @ =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-oOO-(_)-OOo-=-=-=-=-= C.
