pseudo - devices documentation

[Luis Farinas]

We are developping an ADA package to allow ADA programmers to use
sockets, files, pipes and pseudo -devices . We are working on a SUN
network running both SUN OS 3.5 and 4.0.
We have been able to find the documentation we need for sockets, files
and pipes in the UNIX/SUN manual. But we never found the pseudo -device
documentation.
Please, can somebody tell us where this documentation is, or where we
could find one ?

			Thanks in advance.
