Where did you find the DCE one ?

For GNU libc, there are 2 interfaces in the moment, one for glibc 2.0,
and a new one for glibc 2.1, which will fix some problems with errno
and threads. They are not compatible with the Solaris version.

The best is, to look at the libc/nis/nss_nis Modules for the interface.
They should be easy to understand, they will not be generated with cpp.

If you have questions to the interface, ask me. I have written the
NIS and NIS+ modules.

Linux is like a Vorlon.  It is incredibly powerful, gives terse,
cryptic answers and has a lot of things going on in the background.
