The bottom line is that I need to communicate with a process that can
run root privileges. I also need to be able to communicate with this
process via parent/child socket with a non-privileged process. -- can
this be done?
An example would be to modify /private/etc/hosts or
/private/etc/ftpusers.
I had thought of the MoreAuthSample because of the sample "tool" which
is included in the bundle. However, this is really from a Java->JNI
code base which is downloaded into cache, the interface is already set
and I would really like to keep the code as small as possible.

When I call moreunixread, I set fdIn to STDIN_FILENO. The problem I

seen this problem before and know what to do?
There are way too many variables here to tell what's going on.
However, I have a couple of suggestions:
o MoreSecurity relies on stdin and stdout as part of its operation. If
you use printf for debugging, you will encounter problems. Many
developers trip up on this.
o The sample that ships with MoreSecurity (MoreAuthSample) works. If
you have problems integrating MoreSecurity in your own code, take a
look at the differences between your code and the sample. As you
slowly transfer your functionality to the sample, the point at which
it stops working should be obvious.
